What does everyone recomend for a replacement throttle kit for my 81 YZ250? All 3 of the bikes I picked up have some sort of aftermaket throttle with them but are all in a bad state. Any input would be appreciated
Cheers, Chris

Original Gunnar Gasser from John Tittman in Brisbane. Don't what ever you do buy a Chinese replica! Just ask Firko who no doubt will tell you about his experience. J

I use a late model YZ125 throttle assembly on my 250 G and other bikes, fairly cheap and easily replaced. Peter.

Do you not like the OEM "whirlpool" style throttle or unable to find one?

Why work so hard turning a throttle. I have enough trouble hanging on as you know. :)

Ha Ha the colour has gone but still can`t sit on a bike, just sitting on a chair is bad enough. I will just be helping out on the day again. Peter.

I believe all the throttle housings have stayed the same from the 1990 models thru to current, the alloy housing directs the cable to the left which places the cable in behind the front number plate. Hope this helps. Peter.

I go with the first post. The Gunnar Gassar type throttle (whirlpool) is the way to go. If only the fact that every second bloke at a VMX race will have one on their bike too. Linked to a Mikuni Carb via a Standard Husky throttle cable (not expensive either)

All the Yamaha YZ and IT from mid 80s on use the same throttle and cables and all the bits are availible separately . it200l 1984 will fit.Thats what i use on all my YZs.

Rummaged through my spares and found a throttle from what I believe to be from an 84 YZ125, throttle tube is broke and the cap missing but I have the housing and after going through the cables at the local shop I deal at, found an 84 YZ125 cable from motion pro that fits perfect! On the bike now and all works. I will order a new tube and cover and will be good to go!

I use the new KTM two stroke setup's

Thread resurrection!
I run 84+ Kawasaki throttles & cables most of the time. They work well, must be durable ('cause I've ended up with so many good ones), and never seem to be a drama adapting them to whatever carb.
The original 1970s/early 80s Yamaha throttles, all shit me to tears.

Same here Mick. Current KTM Domino two stroke throttle. Far better than Gunnar Gassers, which I have plenty of.

Magura 314 or Gunnar Gasser are the best brand name aftermarket throttles out there. DO NOT be a cheap arse by buying the replicas of both that are all over the 'net. Make sure the Gassers have Made in Sweden cast on them and the Maguras 'Made in Germany'. I won't go into it again (search the forum for another thread on faulty copy gassers) but trust me, the replica Gassers are extremely dangerous and should be banned, I was nearly killed by one and many other racers have found their inherent fault the hard way. If I was a safety scrutineer I wouldn't pass them. The copy cat Magura 314 comes from the same Taiwanese factory so the chances of it being shoddy and dangerous are pretty high. As Mick and Ted also write, Domino (Tomaselli) are also pretty good. My bikes all have Maguras these days.

Mark, the KTM Domino 2T throttle is far better quality than the Gunnar Gasser, ( which I have had fail ) They also offer a far shorter action. Perfect for 125/250 bikes. I think they also can be ordered with different actions.
-
Point taken Ted, I forgot the Domino. At the risk of upsetting Davey Crockett, these (below) are the best quality throttles on the market.....they're machined from solid billet alloy, feature needle roller action and there is no plastic in them except for the clear top. You'd have to drive a D9 over one to break one. The thing that turns people away from them however is that they're made in China for pit bikes. I'm just saying what I've found, I've had them on my bikes with no problems but the flash anodized finish looks dumb on pre 70 bikes....the only reason I don't continue to use them. I don't really care to enter into another Chinese Shit discussion....buy what you're comfortable with.

I buy mine from my mate who happens to be a KTM dealer so I only pay a bit over cost. Dont quote me but I believe that the 2009 KTM 125 has the longest cable so easiest to route on VMX bike. There not cheap but there are some things I dont do cheap on. As I dont ride often enough ( like most ) I find a smooth light throttle gives less arm pump.
