Is anyone running a high comp piston (11:1 to 12:5 to 1) on their stock bore 110?

With a bigger cam will there be any clearance issues?

Weisco makes these. I think a few make one for the stock bore?

mill the head check the ptv

Is the bike still a 3 speed or have you put in the 4 speed shift drum?

I have to keep an eye on what the competition is doing....

No splitting the cases for me, staying a 3 speed, can't tap 3rd at Grange right now.

If I give Andrew the 108 he's gone, provided he can stay up in the dirt.

I say give him the 108 and let him hang on. I am hoping to have my 108 ready for Sunday, or a bike period to race this weekend.

might look to see if anybody offers a thinner head gasket as well, i prefer running a thinner head gasket and doing less milling because it reduces the quench which reduces your chances of detonation.

We'll see you there, should be a good turnout with everyone skipping last race.

Weather is supposed to be sunny and 70!

Rgr, I don't want to go that route though.

alphado · 03-20-2006, 01:10 PM

I did, it ran close to a 134 kit.

Thread back from the dead.

Stock bore hi-comp piston on a 110, for those that have cc restrictions.

Who is the expert on this, need some info please, thanks!

jetcycles · 09-30-2006, 08:01 PM

back from the dead again. . . any other opinios on the HC piston?

Tommyb 754 · 08-11-2009, 10:01 PM

again, up TTT. I think I want to stay stock bore.

Anyone have any experience with the Weisco Hi-comp pistons?

firepower354 · 08-11-2009, 10:27 PM

We sell a .5mm over for $70. Works great. Unless the motor is new, it likely needs a cleanup anyway, and boring to match the piston size is the correct way.

filthyboatguy · 08-11-2009, 10:36 PM

I ended up running the Weisco 53.5mm 11:1 and a TB 55mm stroker crank, works great! 124cc torquer!

I think Anakur (sp) sells a 53mm hi-comp piston if you gotta stay honest. Lookit that beauty! Knife edged crank, lightened flywheel and cam sprocket, primary gear, 4th drum... Sleeper

Z50King · 08-13-2009, 12:02 AM

oh wow, a stroked 110! I have yet to ride one of these. akunar stopped making the high comp piston, and their stock ran out a few months ago

terry, does anyonel make a 53 hc piston still?

those pictures are too big to view on my phone, I gotta view them tomorrow!

RoostDaddy · 08-13-2009, 07:46 AM

I've got a Wiseco .080 over high comp. piston in my bike with the Takagawa hyper cam. No clearance issues. I believe they still have the stock bore high comp. piston available. For the same price I'd go .080 if rules will permit you to.

Akunar has the 53.5's left. There are some 53mm options, but they really aren't much better than the Wiseco.

Sitt311 · 08-13-2009, 06:21 PM

i got akunar 53mm piston, ported head, and hyper cam and it really wakes the bike up alot. more torque and a revving machine. but i need rings for it. can i run stock kawasaki 110 rings?

Did you mill your head or not?

RoostDaddy · 08-14-2009, 07:47 AM

Jbird,

no I didnt mill the head or do any mods to it. Although I have been thinking about getting the head ported maybe over the winter.
