It will be the same spec as budda used to run, except I've balanced the crank, so it should go alright!

If its the XL125S.......it will keep pace with the std FXRs and go all day. The 125cc High comp S piston only has 1/2 a season on it and is genuine Honda......you might go ok.

dont forget to check piston to valve clearance this time huh?

Shout it some new valves and springs.........That was the only unknown part of that motor rebuild........we made it up out of what was in the box, using new piston, rings, bearings, seals and gaskets. It went very well for a 125cc, its the way it should have stayed and I'd probally be riding it now! The quest for more HP made it a unreliable POS.

Unless you've toasted it the black head which hasn't been drilled or welded for the decomp, is the 125S head and was the pick of the bunch. But knowing you, you will go for the head which was ported to the max and has been through a major engine failure.

Nah what I'm gonna do is run the black head, but I'm gonna port it to the max tommorow.(Today-Saturday) Probably. Running the best condition standard cam, and running the 185 piston that you used to use.

I tried using that standard 125S piston before, but it was really flat, I think it might be a bit worn out? Was hard to keep up with FXR's.

I've spent a bit of time balancing the crank to suit the 185 piston so the vibration shouldn't be an issue.

I'm putting new big end bearings, seals and gaskets in it. To save money I'm just using the old valves and springs, as I don't want to spring for some new valves at the moment. It shouldn't be an issue anyway as it doesn't rev too much with the standard cam. It should be pretty reliable, I am cleaning everything thoroughly and am giving lots of attention to detail. I will consider springing for some new valves tommorow if I can get them. There is the option of straghtening the new bent valves out of the blown up motor, but I don't think I'll go for that as I am uncomfortable with the idea of straightened valves in a race motor.

That big bore motor was a pig so good luck and I hope you pull it off. I still think the 125 would be a more sensible option with the amount of time you have, still the CG is there as a back up.

I know you hate them TT but these Loncin 150's interest me. My old frame with one of those could be the answer on B track, with the superior handling would negate the loss of HP. At around $390-490 for a donk ya would struggle to do a "full" rebuild for anthing like that. They are proving themselfs some have been around for awhile now and they haven't died like we expected.

I have also shotpeened the rod and crank.

I'm not a big fan of the chinese motors as they arn't compatable with honda parts as I
have heard, and I have seen new motorbikes with only about 8 hours on them seized.

The other thing is that all the chinese motors seem to be based on a pushrod CG motor which isn't very good for power.
