About to start the next project 1977 ATC 90 any suggestions?

[hdeuce]

I'm ready, what do you have? Can you hook me up with a big bore piston and cylinder so I can just bolt it on?

hdeuce your 90 reminds me of the GPX 177 that Edog built awhile back

thats because I bought edogs bike and parted it out. There are quite a few remaining edog bike parts on this bike.

First all, get some new tires for that beastie and don't overinflate them. Treat your tires nicely, that is your only suspension for now. The biggest thing I find on the 90/110 engines is make sure the engines are properly tuned and running right. #2 make sure all your wheel bearing front and rear aren't causing any unnecessary drag on your engine, your are maybe talking 8hp here. Make sure your chain is properly adjusted and not hanging up and to make sure your rear brakes are set and working properly, once again to not cause any undue drag on the small engine. A nice free flowing air filter and a DG pipe will help wake the trike up and you may want to check your plug to make sure you don't have to rejet. Watch your riding with a free flowing air filter, I mean don't drive through lakes or really deep puddles and don't spray your garden hose directly at the air filter, you don't want your engine to eat alot of water or mud. A cam is a better initial investment than to just bore you cylinder out to the biggest bore, which can be wasteful if you are on a limited budget. Make sure your electrical connectors and ground are nice and corrosion free and making proper contact. It doesn't take much resistance in a 90/110 points system to really make the trike run rough. They are great trikes to learn maintenance and wrenching on. Parts are pretty cheap, I mean they had a 10 year jump start on other honda trikes except for the atc70, so they solid millions and there were tons of aftermarket parts. People just seem to like the bigger engined trikes so most 90/110 trikes get passed up on. You ain't seen nothing to you've seen the unlimited 90s powersliding sideways around a turn. I hope this gives you some ideas to think about. Have fun.

Oh I didn't realize. The 177 was the one that ran into a tree? You sold the GPX motor? I'm confused here.

No, the GPX 177 sat in my shed for to long and had to be parted out. This 1978 90cc was the one that ran into the tree and sat for many years until I got my hands on it. The result is another fun toy at my lake house. No clutch on the 90 (unlike the GPX) making it easier to ride around on
