for you it sounds like no problem, 4spds are sweet, if you want it do it!

 

It would be dumb not to. If you have the money and you can do it, than why not.

 

does this require spliting the cases? Im assuming that it does?

 

Cases will be needed to be split.

 

Im actually going to see if a machine shop can turn my stock one into a 4 speed, as the one from Two Brothers is made out of aluminum and Im not sure how well they hold up.

 

are you shure the cases need to be split ??



im not 100% shure myself but if im not mistaken i dont think they do

 

yes u have to split your cases

 

Has anyone installed one of these. Kinda interested to know myself.

 

The cases have to be split, its not that hard after you do it once or twice. They come apart pretty easily, get a Kawi service manual, the right tools, some 1104 sealer, and a good amount of patience.

Trail Bikes has a steel 4th gear drum.

 

a machine shop would need to write a program to make that drum. its not a regular groove. or a part that they could pull dimensions from. its a lot of work and would be more $ then buying one already done.

 

i would only reccomend the 4th gear if you are doing alot of motarding!!

from what ive heard its useless unless your doing 40+ MPH alot, just dosnt have any pull in forth any slower than that!!

 

Do it! If your already got your motor half apart it shouldnt take much longer to put the 4th gear drum in and then it's there when you want it! right? you cant lose!!

 

I am about to install the shift drum. Do I need a full gasket set ( $50!!!)? Where i can get a service manual?

 

You can install the 4th gear without a gasktet set if you don't tear any of the gaskets as you take the motor apart....It' easy to do but you need the right tools for the job...We use a Mag puller that Classic Honda sales and a case splitter .....We can do it in about an hour once the motor is out of the frame....Be carefule and watch were everything goes when split the cases !!! It's good to be able to go to a parts fish and check out how everything lines back up when you are putting it back together....Pull the top end off and drain the oil and send it to hammerheadmods.com and we will install it for you !!!! Good luck, d-hammehread

 

is there anything else needed or just the drum?

 

All you need is the drum (and of course the gaskets needed for the motor).



I dont think its worth putting the 4 speed in unless you already have to split the cases anyway.

 

I havent used my 4th gear on a mini track yet I always use it on the vet track cuz its wide open.I dont think its needed unless you riding supermoto,or vet,or bigger tracks,I got a stroker put in my motor and since it was apart I had it thru in just to say I have a 4th gear that i dont use on the mini track I barely get out of second and third.if you spit the cases yeah do but if not then dont do it later if you decide to get a stroker or break the countershaft.

 

If you are going to be splitting the cases you might as well just throw in the stoker crank, the takegawa close ration 4 speed tranny, a shift star, and all of the other aftermarket business so that you only have to tear your bike down once!

 

i personally think its more of a hassel taking the motor off the bike then spliting the cases. It's simple.

 

wow so I am pretty sure I am going to get the 4th gear shift drum and a tb 134 bore kit, where do I get the gaskets? Is that all I need or whats that sealent someone was talking about?

 

not worth it unless you have to split the case anyway or do a lot high speed motoard style riding or use your 110 for trips to the mall, grocery store, local tavern...

 

I have the shift drum and it is sweet in the desert !

I smoke all my buddies with 3 drum !



As far as the track goes-i never use fourth though !



Huge difference ripping across the desert pinned.

 

I just dropped my bike off at imxracing to have them install the 4speed drum and hydo clutch. Can't wait to play on the motard track!!!

 

The case splitting is really easy and the Trail Bikes drum is what I run, as it is steel. None of your gear ratios change, but you get another whole gear.... this does allow for more gearing options when motard racing. the close ratio 4 speed trans is really just for dirt use.... The stock ratios are great for motard use. When you put your 4th gear drum in, you will want to use a "bump-start" device or do your own work to eliminate the neutral safety switch that picks up from the end of the shift drum on the left side of the bike. The aluminum drums don't always allow for a good contact, so the result is total loss of spark.



Even if I only rode on tracks that allowed me to get into 3rd, I would still stick 4th gear in it, since the jacking around when not racing is priceless...
