And here's my pit bike finished..... Another bike back from the dead  ;D







And another bike that Honda could of/should of built.... The little beast is ALL Honda apart from the rear shocks (WP) and the pipe which I built from a DG end cone and a home made header pipe from CT125 and CRF230 parts.

Thanks. Everything is subject to change but at the moment, the little four stroke red devil is a keeper and is living in my hallway  ;D

Cool. Motor looks like it belongs in there. Aren't you doing the same thing to an '85 CR250 Rodger?

Now that's an interesting beast happening there silverfox. Being a Honda man, I can't wait to see it finished.
I reckon having the XL swing arm there might be a problem. They are very short making the front of the bike want to lift all the time. Great for wheelies  ;D

As for getting the motor to go, I have a '79 XR 500 and all I did was put a 40mm Mikuni on it, 1mm larger inlet valves, A high lift cam (can't remember the lift but it wasn't the biggest available) and a High comp piston (std bore). It goes well enough for me without spending too much money on a big bore and everything that goes with it.

Can you remember what the valves were out of? and the maker of the cam?? Thinking of trying to fit a lighter flywheel to get it to spin up a bit quicker, but not sure what will fit. Got a 38 mikuni on it now but need to get it jetted right. Do you remember what your jetting specs are?? I have a RM 400 swing arm and a CR480 swing arm that may go it it yet, but will need modding first.

I got the valves made by sending my original to a mob in QLD and just asked for 1mm bigger. The cam came off ebay. I can't remember jetting specs for the XR. I have too many bikes to keep track of jetting. Hmmm, maybe I should write these things down in the manual I have for each bike....

Thanks Ross. Yeah, I always will have a liking for the little XR's..... It's because of XR's that I know how to ride  ;D
