larger

I have a UT2 head I am working on with the valve seats for the 26mm intake and 24mm exhaust. I am going to order a 27mm intake tomorrow but am unsure how deep to have the seat honed out. I know to hone the whole seat larger but how far in to the bowl do I go? I know to machine the whole valve...

anyone used 8 inch rims to get taller tires from a warrior or anything else.

Wanted: A larger framed, preferably with suspension, mini bike frame, roller or complete. Bonanza/Trail Horse/Gilson or larger like a Heath kit/Heald etc. PM me with what you've got available, Thanks

Maybe this is a dumb question but I read that by adding a larger intake and filter to a motor without putting a larger jet will shorten the life of the motor. Too much air flow? I bought the K&N style filter from OldMiniBikes warehouse for my predator. :helpsmilie:

The bike is a Heald VT-1012 with tire clearance issues in the front and rear. The bike calls for a 21x12x8 tire. The Tire that is on the bike is 21x12x8, but when measured for height the tire is 22-3/4" or so .... why? ATV is noted on the side of the tire, is there a difference between...

I installed a predator 212 on a go kart project I'm working on and I got a stage one upgrade kit which includes 36 & 37 jets and a larger emulsion tube, when I installed the air filter kit it was so lean it wouldn't start so i swapped in the 36 jet and it ran good, then I swapped in the larger...

It is currently not running, but it will run, the engine turns over fine. It has a Tecumseh 0HH55 6.5 HP engine. I have the seat foam, but nothing else; so what you see is what you get. The top frame bar has been slightly bent (about an inch upward) to accept the larger motor, but it has not...

Looking to buy a tote gote 600 or larger roller or complete. Also interested in a tule trooper. Please PM me. Thank you

The last gen HS40's they swapped the intake and exhaust so it looks just like an H35. Anyone know if at that point did they just up the HP on the smaller 3.5 block somehow or was it still a physically larger engine block :shrug: Also did they still have mount points in the casting under the...

Thinking about using this since it runs great. 1" shaft so the clutch is going to be more $ but there must be some upside to that larger one? Thanks for any info.

I know there are many many vintage mini bike manufacturers out there. Some are designed for kids and some larger. I am 6'6" tall and looking to build a pit bike for when I go to track with friends. My concern is with suspension bikes I may bottom out rear shocks due to me being 275lbs. So my...

I know we are always calling these bikes Sears Ropers. Well this bike is on ebay right now. It's the larger wheel model but it is the same frame as all the others we call Ropers.

I'm looking for a larger diameter aggressive tread tire. I like the Snowhog but I'm unsure of what size I need to fit the rim and increase diameter. I've searcher but I'm unable to find the exact tire size. Thanks for any help.

Hello all I just scored a nice older DB the kind with the flat seat. I need more torque, it won't climb even slight hills. I don't want to spend a lot of money for an adapter plate or jack shaft. I'm looking for a larger rear sprocket. I'm willing to re drill the mounting holes etc. Does anyone...

Guys I am about to build an exhaust for my 6.5hp clone, and was wondering if anybody has gone with a larger diameter exhaust pipe, and if it affected performance? I have some 29.5mm piping that I was thinking about using, along with a race stinger off of one of my race sleds... Thoughts?

Would like to put 10 or 12 inch wheels on my warrior. Anyone help me find something that will fit. Thanks

Thinking of picking up a larger mini bike.... I know the Broncos and Baja mb200 seem larger any others?

What OEM carb is larger than the stock H35? Want a little more power keeping the original look.
