FXR150 - engine dying at random!

[Henk]

I know where to find the gas cap in any case so will throw that in. Besides I finish work at 2:30 on a Friday and some idea where it all is so should be no issue.
Must admit I get a bit nervous heading out of NZ and into banjo land

Looking at the fuel cap breather is plausible for sure.

I know a fella that races a H2. The middle cylinder nuked a piston when the motor was being starved of methanol, because he had fitted a different fuel cap to the tank during painting. This fuel cap has a small hole in, not the one he drilled specifically for when he converted to methanol..

Sometimes the wiring loom is a bit short and pulls on the cdi connector, just try moving the cdi a bit closer to take any tension off the wiring

Umm, don't you live in WEST Auckland?


Cheers for all the suggestions guy's. Got lots of places to start looking, will do it after the weekend of bucket racing as it'll be stripped naked anyway.

That must have been why my Sons FXR had cable ties holding the plug on the CDI would have been for. I wondered why they were there when the plug was ok and didnt have broken clips on it

14 tooth sprocket on my FXR btw Jase.....

I have got a 14 and a 13, will put the 13 on as Tylers FXR commuting days are over

Dont know why someone had fitted a 16, would only use 2 gears on a kart track like that

I only use 2 gears, anything else scares me!

In all seriousness though maybe it was geared for TRRS?...

Richards high power FXR cant pull a 16/49. I have 11 one one bike and a 12 on the other.

[avgas]

Check ya battery terminals. I had exactly the same thing.
Found a hairline crack on one of the terminals........during some times the terminal was disconnected from the battery........and engine randomly died.....


annoying thing to find.

yes but. . . if a bike revs heaps higher it won't need taller gearing to go faster.

but yeah kart tracks are special.

[Bren_chch]

yer like yow ling says...

fit a cable tie around the connector and cdi so it cant wiggle. sorted, quite common.

I was using the standard FXR150 road-going sprockets at Roys Hill last weekend - 14/49 teeth (2003 model). I did not use the top 2 gears (5th-6th) but the others were fine and suited me on the track. I had to change mid-corner 2-3 times every lap, to be on the power leaving the corners, but it all worked well.

[Arronduke]

Damien,

what size sproket do you use for Mt Wellington?

Where is the best place to buy one?

cheers

[Damien_Toman]

I have been using a 12-tooth for Mt Wellington (12/49) but will try the 14 front next time and just ride in lower gears to see how it goes. My brother had the 12-tooth fitted in Christchurch before I picked up the FXR150 - the bike shop had to use or make a washer to make the sprocket fit. Cycletreads should be able to provide a sprocket and spacer/washer that fits - bring original sprocket with you.
