Is the 88 class going to be checked for true 88cc bikes? I would hate to come all that way just to be beat out of a position from a cheater?

Dont worry about the cheaters.........Zac (Michigan Mafia) has done ok with his 88cc TRAIL BIKES for the last 2 years (2011, 2010) and Derek Rose (2009) Year before that.

Its been on the dyno for the last 3 weeks..............tuner her in for 2012.

Vacuum gauge that hooks up to the spark plug hole. Stock 50's have a 41.4 stroke, strokers 51+. they will pull more vacuum(allot more). Don't have to tear motor all the way down just re move timing cover, mag cover, put motor at top dead center, re move timing gear, make sure at top dead center, put vacuum gauge in spark plug hole, rotate 180 degrees. 41.4mm vacuum spec is xxx and 51mm vacuum spec is 000.

You go home with a motor still in tack you only have to install timing gear back. better than tearing the motor all the way down.

Yeah those boys both haul, I don't expect to win but hate being beat by cheaters. I'm de-tuning my 115 back down to an 88 just for that class and I hate doing it,lol.

The wheelbase for the z50 crept up 2 inches but still doesnt get the 45inches that a crf50 gets? have to get to work on the 3v heads maybe 5v heads guys.

Take a DOHC and do this to it.

/shameless plug on/ FYI, I have a Yoshimura Race head and 52mm piston, new in the box that would own most 88cc setups for those who aren't machining their own setups. contact me via PM to discuss. /shameless plug off/

The rules don't say anything about Fuel Injected 88cc with a little shot of hidden nos for the hole shot. Or an 88cc nitro methane with methanol or alcohol burner.


Dang they did put it in the rules.............Fuel Gasoline ONLY No Nitro, Alcohol, Methanol etc. LOL, But nothing about fuel injected or nos

Lol a little nos would get my big ass moving off the gate!!!! Tore the 115 down with a tear in my eye to make an 88 but should be fun revving the heck out of it.

LOL................EBAY!

Could you imagine having it :aargh4: ...............LOL, I wonder if the piston would last with that little shot of nos without bumping up the main jet

Is a pod filter legal? You can conseal your Nos in that
