stock RCM vs modded RCM drag race

daddysmut · Apr 2, 2006

we ran several drag races just to make sure the outcome was the same each time and it was. i even drag raced my stock GPX motor against the modded RCM motor.

basically, the stock RCM motor has nothing done to it except a TB rev box, air filter, and a pipe (Yosh).

the modded RCM motor has a cam, air filter, CH pipe, TB rev box, 22mm mikuni carb and a modified race head that Cat 5 worked on.

the stock RCM rider (Shakyrick) has experience in drag racing and weighs in at 175lbs.

the modded RCM rider (Slidingbull) is a stunter and weighs in at 228lbs.

even with the heavier rider, the modded RCM whipped the shite out of me and the stock RCM rider.

at one point, Shakyrick and i had a head start riding down a dirt road and Slidingbull blew past us with easy and got about 15 bike lengths ahead of us.

i rode the modded RCM and was pretty impressed with the difference in power from the stock RCM....but in a week or 2 i'll have my GPX motor modded and we'll see how it turns out then

Switch to a 26mm mikuni you won't believe the difference!!!

birddogg · Apr 3, 2006

Do you think a 26 is too much for trail riding? I'm sure it would be great on the track but I tool around in the woods more than anything.

monkeybike_mike · Apr 3, 2006

I run a 26mm on my zonger 125 w/ kitaco irc 14/41 gearing with a 12" rear wheel and I have instant snap from off idle to upper rpm.

birddogg · Apr 3, 2006

I have an Kitaco inner rotor in the garage I've been thinking about throwing in the RCM. Is it worth it? I'm kinda wanting to wire it for lights and just cut the flywheel. I've been putting some serious miles on it lately and would really like to put some lights on it.

change your pipe to a yosh or chp , bump up your carb to a 26mm , add an kitaco irc.T-bolt is working on a 137cc kit he also has Crower G2 cams.

What no HC piston? I'm just waiting for a cam and springs for my RC which will have a HC 56mm piston, G2 cam with HD springs, mild porting, 24mm flat slide, Yosh. exhaust, TB rev box.

Just put my GPX together, HC 54mm piston, Takegawa cam, mild porting, 26mm carb., Classic Ultima pipe. Sounds awesome, bugger to kick over now?

RCM's use 14mm wrist pins Gpx use 13mm Wrist pins I only know of One place that Carries special pistons for RCM's and that is Precision Cycles. Milan has Custom Wiesco Pistons with 14mm wrist pins.

Im interested in how long the modd motor last. If the motor holds up and more so on if your only drag racing the bikes are you dragging in the dirt. On the street or asphault is meaningless unless your only racing pavement.

Got my piston from Vince at RCM and he also has custom Wiseco piston's in the works for the 14mm wrist pin. Now you know of two places.

Really. I know quick guy. Problem is what oldschool posted means something to me if it fits a certian type of riding. Riding in dirt causes drag so depending on how something was built it might reach in a different way. I just see this oldschool guy pumping a business he probably works for. I want to see video in both the dirt and street. I might be interested in the modd if it is real. Thanks for the help cracker from fl. I do my best thinking when people give me something to think about.

Once Again Guy...You know Nothing about me and I asked you not to Include me in your Posts...For your info I work for the largest Railroad in the country as a Locomotive Engineer and am trusted with Multi Millions in equipment with my knowledge and Skill. But at this time I have the MisFortune to have been Diagnoised with a Cronic medical Disability that allows me to spend "Lots" of time with My Passion of Pitbikes and motorcycles in General. I have been asked to Preform testing and Development on Team Motors & Bikes "For A Pit Bike Team" that is being Formed in the New England Area. Along the way if I can pass on helpful info to people in need I do so thats what this website I believe is for. and if anyone or company has helped out and has asked me promote/ mention their Quality products I do so and am proud to help in anyway I can As do many people on this site..... I believe you Refure to it as Kissing A$$!! I call it Most Gratefull and appreciative for such Help!!!!

Thanks Again for Your time

And if anyone of you guys want to know how to make these RCM bikes get up and really go Contact Harris718 on this site he has been Modifying Honda, LIFAN and RCM Bikes for sometime know......I myself have not.

Just know that RCM Bike Motors use 14mm wrist pins (which are different from Most motors) and Custom wiseco HC pistons for these Bikes can be Bought at Precision Cycles not a paid advertiser of this site...

Bro calm down. You promote a company and as far as I am concerned you just stated you work for them to create a race team. If you are putting information out I think it is cool bro. I do not find it cool that you name a company and one in general all the time. If you are not trying to make him a dollar then give the info on what piston and work you need to do to make it work. That is the info I want. Not go to this guy because he is the only one that has them. That is called sales. Im sure your disablement sucks and sorry it happened to you but bolting a part on a bike and running it does not make you a guru to give reliable information. If I had a disability I would be spending every free moment trying to fix it or find out what would make my life more quality. You just observing what bikes are doing. You said you have a disorder how do I know it has not effected your response timing with your throttle hand. How do I know the other bros do not have super human response time on their throttle hand. Show a video with your claims because I believe all you ever do is try to make sales for companies so you can get your super salesman deal. Have the same test rider test all the bikes and clock them it will give you a better picture on how the bike performs. I took a course about workman comp or injuries on the job or off. Guys and gals who are sent on industrial leave for any reason are still on the company clock. Difference is they are now being paid to resolve the issue that lead to their leave. Employees that are doing anything other well on leave are usually just trying to work the system. Im sure your employeer would not be happy if they are paying you well your off to be playing with pit bikes. Sorry if I upset you but I see this all to much. A guy I work with had a nervous break down on the job and was sent on workmans comp for his situation. I have no problem with that. I did have a problem that he got paid the same and did not have to pay taxes and ran into him at a golf course. He had had a few drinks and was playing a great game of golf. Must be nice bro it must be nice.

This Race team has Nothing to do with RCM Products if you bothered to read any posts. And if you Bothered to Read anything you would know that this team is all about PITSTER PRO and the GPX Motors. Which has nothing to Do with My Sponsor Precision Cycles. For anyones Info I am Helping out a Local "Vet rider" that is interested in Funding "out of pocket" and heart a Local New England team to Promote Pit Bike racing and quality and reliable PITSTER PRO and the GPX Motor parts between the 2 of us we have over 40 years of racing exsperiance and what we know is racers help other racers and this is what its all about.

This Thread is about RCM and I mentioned that a Aftermarket Wiseco Piston is avalible with a 14mm wrist pin (which was posted months ago) was availible at Precision Cycles......a Non Paid advertisor of Planet Minis if anyone needs application info contact Harris718 on this site.

I have never ridden or owned a RCM bike so I have no clue what the Hell you are refuring to I support the Shop that Supports me.... and he Carries RCM Products!

Bolting a Product on doesn't make anyone a Guru..But with my Background and exsperiance in Motorcycles gives me a Soild Clue..! thats whats Great about this site you can take The info or leave it. I mentioned my Disability Only because you think im a dealer or work for a company..Wrong again Pal. My problem is incureable but treatable and unfortunetly prevents me from returning to my Carrier job.... It has no effect on My Roosting ability and any other related talents I have on a motorcycle. I always eccept and welcome a good challenge and not just give up. The Info I provide is true and honest and would never knowinglly post false info I am True Blue. I say again I will continue to back those that help me out with knowledge and Quality parts and Customer service. As do many other people do on this site as well as other sites.

again you dont have a clue of who I am and for reasons beyond me I must hurt you in someway?.....you must be some (has been wanabe) Non Bike Riding, fallen company Owner that went down in flames....... looking for Vengence. Cause a "anybody" dont pull the crap you dish out. I must be making an impact and a difference with the time I put into with the Projects Im involved in for you to single me out and take a interest in me....So I'll say thanks for the time...LOL
