Honda GB500 tt

It looked very nice sparkling in the rain today Spank - did you find a suitable mirror?

[SpankMe]

The wreckers next to Holeshot had some new chromed bar end ones but were $112 for the pair. I'm sure I can find ones that aren’t so expensive. Or the same for cheaper if only I could remember the brand name. :unsure:

Can anyone read Japanese? Want to know if the 601cc requires boring or is just a re-sleeve. The google translator doesn't really make it clear enough.

Dunno,but it looks like you'll end up with an 11.2:1 compression ratio,you may need to buy a drum of Helecopter fuel to run it.
I've got a similar problem with my XT400 to XT600 conversion - it's got a big bore Wiseco piston,busted.The next size up is 10.5:1,so I'm just going to stay with the 621cc 97mm piston which is standard compression.101mm needs a resleeve for the Yamaha.

I can't understand it completly, but it doesn't give any details about reboring or resleving.

Can anyone here help answer this.

Dude does it not get confusing?!?! This frustrates me too, as far as i understood the GB was like hte XL/XR600's except that it is far detuned with a massive flywheel and a few random things like that, timing was further out, gearbox was different. but that was it.


and the 88-onwards model XL/R600 i would imagine would be different to the GB500. I have manuals for those things all over the place here somewhere?! hell i have one of those XR600 engines with the wiseco piston kit all brand new waiting to go in, has been for the last ten years... hopefully to be put in a homemade machine in january

Spank I think for a job like youre talking about you need to hand the motor over to an expert. I would strongly suggest giving Alex Gee a ring -Hes a bit of an (old) Vtwin and single engine nut.
Sometimes ya gotta use the trial and error method --and squish a lot of blue tac before ya get it perfect. (the blue tac is to test valve to piston crown clearances

That was something I was thinking would be good to deal to
Lighten the flywheel -instantly raise its ability to rev.
ya gotta love singles-- only 1 of everything to work on

What you should look for is a S/H Honda Dominator motor, electric start 650cc, keep your GB engine as a spare.

So ya think Colemans mechanics are not up to it then?

Where would I get one?

Out of a Honda NX650?
sorry, couldnt resist! Maybe some of the N/I wreckers may have one? Peter Glidden Farm & Trail perhaps, possibly out of Oz? Not sure what it would cost maybe $1000 tops? Or alternatively a late model XR600/650 or XL600/650? How much you want to spend? Could buy complete bike then flog off what you dont want after?

If ya want a chrome muffler for it, WFO make some good ones. At a cost of around $120 each. Reverse cones (unsure of p/n), straight throughs(unsre p/n) or Dunstall replicas(p/n 448-0011)-have one of these fitted to the 550/4 and it seems to be lasting ok.
