Can you please post a few photos of the driven sleeve in place? I have put a sleeve on the driver I'm wondering if your idea to put one on the driven might be better. Thanks

It's all good deadpixel. I haven't even started on the carb yet. Slow and steady wins the race lol. I'm way too new on these little engines to jump in too deep lol. I definitely interested in what I at home can do after porting, filing key way to get more ponies. I like the idea of tinkering to...

I was able to get a dremel bit through the port to get to the short side. But I wasn't sure how to smooth it out. Thin emery tape makes sense

I found Dyno Don's page this is where I had the confidence to get in and have a go.

That makes sense. Man I love forums. Even though I am an old car mechanic you can't get this type of experience unless you're in a performance shop, which sadly I'm not. thanks heaps

Ole4 I noticed you have head studs instead of bolts. What size are the studs?

Are you talking to me or deadpixel ? He has has gone further than I have.

What he said lol. I'll be spinning mine no more than 5500-6000.

I have given my head to a friend who does valve work for a living he has re-cut the seats and ground the valves. They look so much better than what they did. He said they were no where near right. Ill see if I can find a bit like that at the hardware store I do have a dremel bit you can replace...

I have decided to jump into the world of porting. I have started with removing the sharper corners and around the valve guides How much more can I take out before I lose too much bottom end? Please be gentle it's my first attempt. I still have to finish them off I just want to know if I...

Ok thanks. I wonder whether you need the gx vertical coil to go with it

Dragging up an old thread here. Has anyone ran these flywheels? I have been given 2 to try

Hmm. Something has made the cam go like that. It's leading down the path of the being faulty. Have you heard back from BSP yet?

What if it was over shimed? I don't know if these valves springs have been shimed but if it was coil bind this would be my guess. Got photos of the valve train bwl?

Good to know. Thanks

Will adding a lash cap and correct retainer to the intake side on a stock clone motor give a noticeable seat of your pants results? OR is this mainly for performance engines? I'm only running air filter/ jet and exhaust upgrades at the moment. I did just order a 14cc head so will be looking at...

I'm trialling a sheave to stop the driver coming all the way together to get into "overdrive". My first test was 8mm and it didn't get into overdrive but wasn't1:1 either. Do I have now made the sheave 6.5mm to see how this goes. When the tc was not modified it my engine would only rev to 3700...

Would also love to know the bando belt part number..

Does advancing the timing make that much of a difference with the governor in tact?

Its the belt itself that a Asymmetric not the pullies. Asymmetric belt has one flatter side and one angled side, a symmetric belt has two angled side hence the V.
