Hey guys the colour of the engine means jack! Suppliers can order them painted any way they like. The main difference between the rear and front mounted clutches is that the internal design of the engine is different. These are still good reliable engines, its just that they have a different...

no don't think so. Team Show and Go Australia your sudco dealer here in Aus. One stop carb shop.

So leroy, ya thread got jacked a bit...hows it going with the jetting? You guys also realise the carb sold as a 30mm on ebay has the 100 main jet (I think, by memory) if you want to trial it out of a mates or something before buying one.

A tad pessamistic... don't worry any longer about the clown from zero brains racing. He is just another home business guy trying to sell you his little velocity tubes cause hes gotta make the little mini lathe he bought last year pay for itself. I have been over his site and was not that...

The biggest problems people are having IMO is they are not even remotely following a methodical and thorough tuning procedure. Also there are cutaway changes, needle tapers and carb porting which all can be neccesary sometimes to get dialled in.

Pitster motor is jailing.

Those forks and shock are not going to ever be good to work with, but you could try replacing the fork oil with a 5 or 7 wt oil. The shock reduce the spring preload and reduce the gas pressure in the shock down to 40 psi or something. If your not comfortable pulling these items apart, then just...

Any engine with oil feed holes from the crankcases must be run through a cooler. You could run lines from the head if you joined the two case outlets with a short line. But these two outlets must be joined. There is another way of doing this internally but it requires drilling out a passage...

Confirmed ^^^^^

Hey I know where you're coming from sixeven, I have been running businesses myself for a while and had a new wave of products change my industry forever and forced me out. But you can't fight these things only go with it or get out. There will be a transition period for a while where all who are...

I of course agree the honda engine is built with greater quality control. I was taking this as a performance comparison. All the engines listed are using Honda's design, no one can take that from them. This is the only reason for even remote success of the China engine companies. I have, and...

Don't worry too much, 99% chance it will run good enough. BTW i got nothin else to do ATM so tuff....go watch telly if you can't handle reading anything longer than a poorly spelt instant message.

For what ever its worth (two cents) If i was running in the motor (just ran one in two days ago) i do this. Most carbs will come reasonably jetted to at least run fairly well. Don't worry about trying to tune it while running in cause the way it runs will change as it runs in. I run a carb i...

Only you can jet it. At is near impossible to tell you what to try unless you do your own testing and report back step by step your findings then ask for recommendation which way to go.

I asked cause i have seen some really nicely polished carbs and manifolds on monkey bikes and such. For the inside of the manifold, it is usual to hone the casting using 80 grit rolls until the surface and bore is uniform. Also to do the plastic adapter and match them together perfectly with the...

Well basic carbs aren't really designed one way or the other, some more suitable for one or the other, buy design, but basically they all have a choke size, deliver a metered ratio of fuel throughout the throttle range and have a mounting for manifold and filter. Carbs have been getting swapped...

Thanks cass, i was told to ice it and they gave me neurofen but i never follow instructions...instead i,ve been getting heat into it and laying doggo. I have seen quite a few cases of this myself playing league, then later rugby, also had a mate do it bad diving for my fifth wicket in grade...

I know I just posted this in another thread but I'll put it here as well. To get these 140 engines really going you must ditch the Pitpro and DHZ supplied exhausts or any other crap china pipe. I really can't believe the exhaust DHZ is running on his 140. I know this is probably one of the most...
