Problems with the emulsion tubes in the carbs? This bike has FCR flatslides fitted so I'm guessing it shouldn't be a problem

Is that the one from Welly mate? We have a Trx .Dont find it specially hard on tyres and it is punted along .Even with Fcrs your lookin aronnd 85 - 90 at the wheel.Ive read ya can get them over 100 RWHP with a big bore.All good usable power tho aint they.
Yes they do use oil,ours about 500 ml per 1000 Kms if ridden quick.Much more than that Id be looking for a reason,Tho it varies from bike to bike
Bit noisy in the timing chest area,Pennzoil shuts that up a bit if you can get it
Im sure the Ohlins will help wiv tyre wear Has it got Gold v/v emulators,highly reccomend them Enjoy

Yeah mate, pearl white with a red frame, currently at Motomart waiting for me to pick it up.

A guy on the forum I visit is aiming for 125rwhp after a 907cc kit, adjustable race cam, FCR's, full race pipe and a lightened lightened crank.

From what I've been reading the bikes that use a fair bit of oil seem to have been run in lightly, the ones that were ridden hard from day one don't seem to use any! I think the problem is something to do with the factory piston rings not being a very good fit - something that was later sorted out, but most people seem to get around the problem by putting in a big bore kit! I've heard of people using up to 1L per 1000km! Whereas others are down around the 50-100mL mark.

The power delivery was what took me by surprise - torque like a twin, but far more rev-happy. I also like the looks, and it handles pretty sweet with the Ohlins in the rear. Not sure on emulators, but James Deuce took it for a spin and he said it probably does - I'm going to do a 'running gear service' soon and will do all the wheel/swingarm/steering head bearings and will check the forks out at the same time. It need's to be resprung front and rear as I'm probably just short of 110kg with my gear on.

I'm looking forward to picking it up, to bad I have work this weekend otherwise I'd be down there already!!!

Fun when on the gas, but hard braking has the back locking up and skipping all over the place

Thats because of the damper rod forks that give the bike little braking pitch control.

Dont bother with the M1, it's an out of date tyre. If you want metzeler, go for the M3. I'd recommend the BT016's however their grip when cold is lacking, but fantastic otherwise.

[Devil]

Of course a Pilot Road 2 is always a good option.

[Morcs]

Second the PR2, with a 2ctPP on the front.

Gareth dont both spending any money for increased power - otherwise youd be better off buying a TLS and spending money on its suspension.

From my experiences with riding a few TRXs, the brakes arent fantastic, but with a wee overhaul and braided lines they improve a lot.

Get the suspensions setup reasonably well (they are actually quite nice handling when they have a bit of wallow to them), and see if you can source a dynojet kit for it.

[R6_kid:Me]

Heh, the only way I'm going to get more power out of this bike is to get a big bore kit or turbo it.

In terms of 'power upgrades' it has 41mm Keihin FCR Flatslide Carbs, a race cam, and a full 2-1 race system. Also has an Over Racing CDI which includes a TRE, and also takes the rev limit up to 10,000 (from 8,500).

It's got a full ohlins rear shock, and presumably emulators and different springs in the front. Brake wise it has Lockheed AP Racing calipers and a matching master cylinder gripping full floating cast iron discs (that actually float properly!). Braided lines all round too.

It goes, turns and stops really well. The only thing I need to improve are the tyres and myself. Got a set of SuperCorsa Pro's on the way, and will be saving up for some 'sports' tyres to go on after they are done.

I'm also on a weight loss plan, so that should help me free up some HP as welll!!!

Sounds pretty sorted.
Dyno?

That's 'cause it is! No dyno yet. May get the treatment soon - once the airbox arrives.

[jimbo]

Do you need a standard air box to drill and play wiv mate? Have a TRX we are about to part out.PM me If Ya Do

Sorry to dregde up an old thread ...

I have a friend '95 Yamaha TRX850 that has a speed limiter on it. Any ideas on how to get rid of it?

[James Deuce]

Yes, and I have the documentation for it, but it means losing the sidestand cut out. Which is more important? Breaking the law infrequently or falling off because the sidestand is down?

I was kinda hoping for a "cut this wire", "install this resister", or something like that.

My friend was wanting to go to a track day, and hence desired to loose the speed limiter (legal fun!). But I'm pretty sure he would rather have the side stand!

[James Deuce]

It is a "cut this wire" trick, but it removes the side stand cut out switch function.

With the limiter removed, do you know what someone could expect the top speed to be? Just a little bit more, like 200km/h, or is it capable of a lot more?
