5 min removal of bearing race from crankshaft

I put a brand new bearings in top end only to discover the crank was twisted. So I put the crank in the freezer for a day. Stood up crank in my vice. Ran around race with a small butane torch for 20 secs. Tapped the crack between race and crank with a fine chisel. Race moved. I repeated this 3 times...

Changing Rally cylinder, need to remove the engine?

I'm going to put a lot on my Rally 200. I know the head and cylinder won't clear the frame, unlike a PX. But I'm wondering if I can support the engine, just remove the main bolt, and pivot the engine enough to clear the frame, leaving all cables and wires in place.

Re: POLINI 210 ALLOY

Hi, I'm about to fit on on my Rally. To get enough clearance to lift the cylinder off, do I have to take engine right out, or, can I just remove the engine bolt and swing the engine out a bit. Leaving all the cables in place.

Cheers

Re: problem with a hyrdraulic in-board front disk backplate

Tx. Mine was a new back plate from Beedspeed. I had to drill out the hole to 12mm, clean up the threads in the oil nipple, and the speedo drive holder would not fit in without getting the powder coat off. That's the kind of thing I expect if I buy off of eBay, not from a shop.

how many amps will the horn button support?

Hi,
going to add a horn louder than the stock duck-fart. I'm converting back to a battery, so will have DC power. I'm wondering at what kind of amperage will the horn wires melt. Above that I will put a relay in place.

Tx

Re: Extra Long Throttle Cable

Not all bicycle shops carry the right cable. Phone around first and ask for a cable for use with a recumbent bike rear gear selector. These are really long. I keep a spair in my tool roll as you can use it anywhere in a pinch. To cut it down, I find I get the cleanest cut with no fraying when I use ...

problem with a hyrdraulic in-board front disk backplate

Hi, I recently tried to install this on my stock in-board disk. The axle would not go through. I have 2 axles on hand, 11.97 and 11.99. My stock backplate diameter is 12.09mm. The vietnamese made hydraulic backplate axle hole is 11.89mm. It is powder coated. Returning it back to the UK vendor from C...

Re: gear help: GT 200 on Jet200

I put my original front sprocket back on, so now stock SX200 gearing, and yes it pulled much better. When I tried to do a top speed test I kept getting stuck in traffic so gave up trying to go faster than 110 kmph, It will have to wait until spring now (I'm in Canada). As an experiment, I also switc...

Re: jet 200 tourer?

Hi, I own 2 Jet 200s. One I have kept stock (even original ochre paint). The other (early SX panel model) I have tuned. This one I did in stages, so can comment. The Jet 200 is a really good stock bike. If you have done nothing to the head, the squish is likely pretty big. Take the head off, put fre...
