iv got a tak88 kit with stock head my question is a have a complete 70 motor laying around would it be a good upgrade to just put on the 70 head?

i think the 70 "e22" head has bigger valves. better.

youll be alot better off running that 70 head, throw it on there with the carb and intake and you wil be set. not quite as fast as a race head but not too far behind

Figure in a domed piston, or it will be a slug. The 70/race/e22 chamber is a lot bigger and needs a dome for compression.

Is this a e22?eBay Motors: Lifan Head with valves pit RCM (item 330251360860 end time Oct-07-08 11:38:40 PDT) Looks like one from the specs.

firepower354 · 10-07-2008, 07:06 PM

The eBay one is actually a little nicer port than a regular e22, plus bigger finning. I hear they can make a decent amount of power, once a little port work is done

I love e22's once ported they are an excellent cheap mod. Get the crower G2 cam at AHPminis and you will be hauling booty.

Correct me if I am wrong but does "domed" mean the high compression piston? I have the same parts so I want to make sure I get the right piston.

norcalklx · 10-07-2008, 10:04 PM

how much more comp. do i need in a piston? Could i just mill the head to make up for it i really do not want to swap pistons yet.

firepower354 · 10-08-2008, 04:22 AM

Milling the head won't do it. You'll fight cam chain issues, and still never get over 8:1 compression. Buy a $43-59 piston, ya cheap fuk

Thanks. Ordered a couple.

firepower354 · 10-08-2008, 03:52 PM

TB kit to complete the head is aboot $30. Email Mike and tell him you want a race head spring kit. Comes with everything the eBay head is lacking, except a cam. Run a China 5.5 takeout for trail and mild MX, DrATV ($36-45) for a better top end. His ad says long cam, but I've got both before, so I'd wait to get them to order cams.

I would throw your 88 kit on the 70 bottom end along with the 70 head. It has a better clutch and tranny ratio.

firepower354 · 10-08-2008, 04:23 PM

70 trans is the same as 50, but the primary ratio is taller. Same effect as dropping 3 teeth on the rear sprocket. 70 has a higher volume oil pump and stronger clutch, beefier con rod, though.

Thanks. Probably just end up with a china cam. It's a back yard buster.
