Bigger rear sprocket - yes. Smaller front sprocket - maybe but this will result in accelerated wear at the chain pin/bushings interface. Expect more frequent...
Hello, I can not answer about the differances between the head casting numbers but from what I have heard they are likely interchangeible. The valve seats...
Hi Nick, You can test the valve seats by pouring gas into the head chamber when it is upside down off the engine. If the chamber holds the gas for more than 30...
Used to? Still do! Now that you mentioned it the Easter Bunny would work well on a pizza. Next time the "CATS" bring in Mr. E. Bunny may have to share it with...
Find its powerband and stay there on hills. You have to rev a two stroke and gear the sprocket to get there. Don't try to compare it to a CT or any 4...
NYLON GUIDE??? Ohhhh-ohhh.....I've had that carb apart several times, cleaning, fiddling, etc..and never noticed a nylong guide...I fear that might be the...
Bob,yes the ct90 would out perform the 1980 ct110 with out dual range off road. We think that's why Honda went back to the dual range in 1981, they where...
Changing the gearing will help by letting the engine run in its power band. Also clean out the exhaust and check the exhaust port in the cylinder for any...
Mike is correct. I own two ct90's and a 72 TC90 Suzuki. The Suzuki is rated at 11.8hp (compared to around 7hp for the ct's) and the TC model has a two speed...
Hey Kevin, I agree with Mike 100% and a gear ratio change could not hurt you a bit for increased low end torque. I spent a few weeks one summer on a early 80's...

I just finished rebuilding an '80 110. And tho I've never taken it off road, it definately has more pep from the start than any of my '90s... including the...
A novel approach! I really liked how you hid them inside the triple tree reflectors and the rear taillight lense. Nice work. I would like to do the same to...

Hi Nick, There were at least two different head designs for the ct90. And they ARE NOT interchangable! Wich one of the two, if either will fit the jug to your...
Don't the s90, the cm91 and the cl90s have a longer crank stroke? I remember Ross from out east taking a crankshaft from an s90 and milling the end of the...
I bought one of the performance camshafts and the hole for the timing advance is to large. I am attempting to hold it in place with lock tite. Do YOU think it...
No, I don't think it will hold... you can go to your local fastener supply shop or better automotive supply shop and get yourself a hardened steel dowel pin.....
Chuck, you'll need a 3mm x 10mm dowell pin for HI-PO cam from the DR. Do a search on past posts. Mel - Yorba Linda, CA ... timing advance is to large. ... it...
Chuck, I didn't mean that the dowell pin was available from the DR. But you should be able to find one at most hardware stores. Or grind down a 3mm drill bit. ...
