Honda / Re: 82 xr500 front forks spongy
« on: March 16, 2020, 09:38:38 PM »
Thanks guys I will try both those and see how I go I think I just had atf so that’s like a 10wt I believe so I’ll definitely try a couple spacers and thicker oil.

I have another 82 500 that has a wr usd front end which is obviously light years ahead but I want to keep this one fairly original just half decent over bumpy stuff.

Honda / 82 xr500 front forks spongy
« on: March 16, 2020, 04:10:16 PM »
Is there any mods I can do to my 82 xr500 front forks to stiffen them up they are really bouncy I have put in a stiffer rear spring to sort the back out because you could bottom front and rear easily.

I had some stiffer rate fork springs but they didn’t fit so it is stock front end currently with stock oil height any ideas appreciated, thanks Michael.

General Discussion / Re: Gas BBQ conversion to natural gas
« on: October 28, 2018, 02:52:50 PM »
The thing with bbq’s galore is they aren’t licensed converters so they don’t know what they are really doing they just chuck the reg on and a universal injector which drill 54 is close for a cast bar burner.

As Hoony said lpg has a higher heating value so when you convert you size on mj/hr so lpg and Nat using the same mj doesn’t necessarily equal the same heat you can go incrementally bigger bit go to big and it’ll burn floaty and even though there is more gas there won’t be enough air able to flow through the burner so it won’t get hotter after a point.

Also a lot of gas taps do or don’t have turn down adjustments this is the low setting so if you convert an lpg bbq to natural and when you turn it back to low it is to low and goes out this is the turn down sometimes there is a screw on the gas tap to adjust this some times it’s pull apart the taps and size the turn down hole that can be a pain.

But you won’t blow your self up with natural gas it’s heaps safer than lpg but there’s is differences like heat value products emitted from burnt natural gas is a lot more than burnt Lpg lpg is heavier than air natural gas floats away.

Going to recheck every thing and leak down test etc etc ordered a new piston so I am just waiting now.

Also it doesn't worry me if I am not sure what caused it as long as it doesn't happen to me again.

No I definitely had all my fuel mixed never got to use my spare fuel any way.

And yeah I got medium stuck ;D I didn't need towing out like my mates in the big dodge setup in the same area I just needed a bit of a push to get going thanks those guys if you are reading.

It's not a pe piston it's a maico 490 piston my crank isn't standard and has a different rod in it and you can probably make out the barrel spacer in the pics so it's a pe 400 cylinder yes but the rest is all different.

I will order another one you live and learn with these type of things it didn't really even upset me I was only spewing I didn't catch up to ride with my mates in front of me and I could see how it could cause some havoc being so wet bikes under a lot of load and I got a bit carried away trying to see what it could do and it was flying when it seized.

May not have ran to well for me but it handled and looked good at least.

I will probably run mineral oil from now on and I am going to start at 20:1 the oil I was using I noticed it wasn't making much blue smoke but I just put it down to being a fresh engine.

Thanks guys I'll order another piston and get the aluminium off the cylinder I'm also going to do some plug chops when I get the chance and look at getting my jetting spot on pipe and muffler is new and unrestrictive I was happy with how the bike handled my forks and shocks worked a treat I was a bit rushed in preparing for the event so I'll make sure it's well and truely sorted for next time.

I was wrong ring locater is still intact so possibly may only need a new ring?

Yeah I was at harrow I was on a road when it happened but flywheel hadn't moved yes it was a powerdynamo one 12v I'm going to take it off and lap the crankshaft and flywheel with valve grind paste I had a mate put the flywheel on after it span but not sure if he did that so I will do it as precaution any way.

I was way to rich early on and couldn't rev out played with the carb and got it to rev out I might go back to 20:1 though as that's what they ran stock

Thanks guys I will get some pics of the piston as well and it happened at fairly high speed over shot Where I was supposed to turn and then it died when I was going back through the gears.

Well taking a look at my pe400 after it decided to stop on the weekend I thought my flywheel may have slipped as it had before but no it has lost nearly all compression big time so I pulled the top end down.

so straight away noticed scoring front and rear of cylinder and I didn't take a picture but it looks like the piston ring locating pin is gone so I am assuming that's what has caused the scoring with the ring then having to much end gap?

looking for thoughts will the cylinder need rebore or be ok running the same size piston and what should I look for to make sure it doesn't happen again, thanks Michael.
