KTM990 throttle snatch?

[buzzard]

i should also say that despite the fuel problems and throttle snatch i have expereinced recently i wouldnt change the bike. It is bloody awesome. Filtering through the Auckland rush hour traffic is a breeze and the bike is big enough to scare most of the car drivers out of the way. Those that dont move.....wel that why we wear boots with steel caps isnt it?

Does anyone know a mechanic (in Auckland) who knows these machines and tune them well? I know that John at Amps used to do a great job but left for greener pastures at Haldanes.

Gavin at AMPS has left as well, and he was the main KTM mech there.

I would give Triple X Moto a ring, sure, my bike goes there, but they also run a fleet of adventures for motorcycle hire, so I would imagine they know them inside out.

Hoping things have improved but also hoping that will post on here so others can benefit from your investigations. Sounds like there is a cheap back yard bodge (or two) that works well.

Yes Ryan, there are a number of free and very easy fixes that can be DIY'd, but apart from Buzzard, who is very happy with his wee snatch, and CM ( who I have PM'd) there are, apparantly, no other 990's in NZ with any throttle problem! So we can close this thread down

Cheers all. j

Especially as the 990 comes with a subscription to KiwiBiker in the glovebox

Brief update.....
I finally got around to pulling the throttle apart and found I already had the G2 200 cam fitted to my bike so that may explain why I find it controllable. In the interests of science I fitted the 400 cam (the softest start version) and am very pleased with the result! A lot easier to control from start off and at low speeds a lot less of the on/off power delivery. I did a 500km ride around Coromandel yesterday and noticed the reduction in tension in my right arm. Previously I was concious of the throttle all the time and now it's just one more part of the bike, not "the" part.
It is still a bit of a handfull at just off idle in slippery surfaces due to the fact that any throttle gets 20hp trying to turn the wheel but once past that point I now have fine control back to the throttle.

Consensus:
Modify the throttle "cam" to slow down throttle movement, well worth doing.

Well done Iain, glad to see I am on the right track.....I was wondering if I was in a paralell universe for a while.

For those 'lurkers' out there......you can save, currently, around US$206 with a file!

BUT WAIT....THERE IS MORE:

I'm just home from a majic 2 day rotation of the East Cape on the Kt. I did lots of hiway, LOTS of tight windies, ventured down some of my favorite gravel sections( yeah I know....you just can't imagine where I mean eh?), with fast sweepers in ballbearing finish, super TIGHT knarlie shit in larger fit( rox that is...), generally a BROAD range of surface and skill level.

RESULT: Pirelli Scorpions SUK bigtime off seal: weight the front a bit and you can cope; on the seal they are the deal! Oh wait, you wanted to know 'bout throttle snatch didn't ya??

Well, I fuckn fixed it totally! NO problems at all, no pissing around with the dinasoric 'KTM start-up fuck around'....oh no, just hit it and ride it!!

Fuel economy? Is total shit. 14.6 - 16km/L, no better or worse than before my conversions. Looks like if this bitch is going to Oz with me I will be forced to try and lever on an Aqualine. Bloody INEFFICIENT motor/EFI system but there you go.....you pays yur monies ya takes yur chances!

Had a great time, just love that area! See ya's!!!!

Good to hear Jamie, did the secondaries removal affect the overall performance, thats on my list for later this week? For reference the difference between the G2 100 and 400 at the start of the action is about 3mm, so probably (I don't have a stock throttle) about 4mm notched out of the original cam....how's that compare with your experiment?

I have to agree about the MT90's as well, I was finding it hard to load up the front enough to gain traction....time for TKC's.

Just out of interest, as you're a similar size to me, how do you find standing on the 990? To get the front to work I have to apply a lot of weight (what there is) over the bars and I can't say as the ergo's really work.
The pegs are too high and the bars too low, I've started a thread on ADV and have had a bit of good feedback there if your interested..in Orange Crush.
Suggestions with merit so far seem to be wider pegs (more leverage) and bar risers. More experimentation to come!

Wow at last we are past the throttle snatch ha ha.

I have put new tyres on my bike, I have replaced the rear with what came standard and on the front I have put a TKC, this seems to be a common fix. I now have more confidence on the loose ball bearing type surfaces. I also stand up on the loose stuff, that gives me more confidence as it puts more weight on the front wheel.

However when I stand I am very conscious that I am on the outside edge of the footpegs so I do plan to get wider pegs. Have you see this write up on ADVRIDER - http://www.advrider.com/forums/showthread.php?t=339722

He has put on wider pegs.

Ian if you are getting wider pegs keep me in mind as happy to order with you.

Overall performance is now very snappy( apart from where I had the problem - sportsbike like!)

I have to agree about the MT90's as well, I was finding it hard to load up the front enough to gain traction....time for TKC's.Michelin Desert or T63 for me... you can stick anything Continental....they are shit tyres on other appliations ie tractor or car tyres!!

The pegs are too high and the bars too low, I've started a thread on ADV and have had a bit of good feedback there if your interested..in Orange Crush.The bars are too low for standing attack, unless you are 4foot fuck all! Personally I will not change anything except the front tyre....I'm a lazy little prick who likes to stay on his fat arse.

I will not be using this bike for its intended purpose, it will mearly be a 1/2up ALL TERRAIN( Multi strada) tourer for here and in Oz( + Aqualine!)....I have a very well sorted, dedicated adventure bike that will walk over the 990 in all but hiway work, so why would I bother and have the unpleasant task of humping a behemoth bitch like this around tight knarly trails? I belive it would need a much 'bigger' man than me ( + skilled also!!!) to be able to be comfortable/capable off formed roads on a 990.

Nice one Mike.

Glad ur so well fuckn sorted.

Thats just the attitude thats prevented a good discussion of the topic

[Crisis management]

Thanks for the feedback guys, it's all appreciated....time to buy some tyres and fiddle with stuff it seems!

I will not be using this bike for its intended purpose,.........etc

For my sins I am commited to one bike to do everything (except trail rides) so will need to make the 990 my sports bike and adventure bike, it does the sports bit ok but I need to practice the off road part of the adventure biking a bit more and get it set up so I can extract some of the performance its capable of.
DJ, thanks for the link, I will have a look at that tonight.

Oh well it looks as if I will just have to suffer through the trials of spending time and money on the bike!

I suffer with you Iain. I am finding myself getting harder to please the more bikes I go thru( Good thing its not women eh!!). I seriously belived the KTM brand to stand for a well sorted machine: you know, top knotch components in a focused package, the kind you buy and ride!

So I am naturally let down by KTM that they left a small but significant chink in their otherwise superb well engineered bike.

I have solved the 'deal breaker' problem.

I will bite the bullet on the tank issue and fit an Aqualine while in Oz.

I tested screen heights with your suggested coroboard mock-up and tonight fitted the KTM 'touring screen'....the xtra height suits my stunted stature and gives me a 'peacefull' work enviroment.

Tyres....well they don't last forever so its no issue to change at the next new fitment is it?( Take the advice of one V. Rossi.....fit something you REALLY like and trust to the front.....and something round and black to the back!!).
