failed MOT

Took bike to what I thought was a freindly garage but they failed the bike on the revs being a bit wobbily (I told him put it in gear let the clutch out and when it's under load they settle bcak down

) but he said it needed sorting. It settles back down to 2500rpm without putting it under load so I don't see the problem I could understand if it was excessivly high.

He also said the wheel beading had a flat spot on both sides and failed it on that too. althgough I;ve not hit anything with it so it nust have gone through the mot previously. Still if it's got a wonky wheel I can understand his concern.

looks like a call to ams for a new wheel and carbs then!

the engine doesn't even need to be started for an MOT. Its not part of the test. Only reason for starting it is to be sure of enough free play in throttle cable or if the battery is too flat to work ancillaries.

Carbs just need properly setting up.

isn't 2500rpm a little high for tickover? i thought most ticked over between 1000 - 1500rpm?

Depends what you like really, i set my tickover to about 2500/3000 when i plan to go for a country road blast and around 1k for commuting through town.

He shouldn't be failing the bike on jumpy revs as thats not a part of the MOT plus it's quite normal for ZXR's to be a little jumpy when the idle is set wrong. If you want to fix it just give the idle speed adjuster a small turn, rev the bike if it doesnt settle properly turn down a little more and so on. It'll still do it once the engines hot again though.

I hate it when MOT testers fail your bike on "Notchy" head bearings, It's quite obvious when head bearings are actually notchy or have play in em, a guy who does MOT's in my area failed my 400 on head bearings after i'd put brand new ones in claiming they were notchy. I did nothing to em took the bike for a retest and he passed it, i told him he could f*** off and issued a complaint with the ministry.

yeah I am not best pleased the tick over is about 1k normally but when you give it a rev they only settle backdown at 2.5 ish then put it under load and it goes back down again. He said he had to fail it as the revs didn't shut down properly.

Still he didn't try and screw me by offering to do the work just said to bring it back in 10 days when I'd had the work done for the free re test. I've got a set of carbs coming from ams-motorsport.co.uk and a front wheel. I'll drop the bike off to a local mechanic tomowwor night and see if he can fix the revs problem. :smt013

You'll need to balance new carbs as well you know.

Be cheaper just to do that init.

As for the MOT, I'd just report the guy to the ministry as has been suggested. He clearly hasn't got a clue what he is doing ..

Re: 'notchy head bearings' its just a license to print money init. I have had no end of bikes fail for this reason and to this day I have no idea what they are talking about when they try that one. Its evident when bearings are notchy - to get to a point of wear that they actually feel lumpy, they'd have to be _titanically_ fecked.

fortunately i have got a good mot tester that i use. he will advise me on things but not fail it unless dangerous - i spose thats all u can ask for

my zxr400 was funny on the revs, would have to blip the throttle sometimes for them to settle at the right idle speed, but never got failed for it

Which one/where? I'm only an hour from you and it would be worth travelling for an MOT, my local lot are cowboys.

they start the engine to check noise levels as well. Im not sure if they can fail it on a high ideal tho, uless its somthing to do with emission's ?

Post by **Jamz** » Tue Jun 05, 2007 11:29 am

Emissions aren't part of bike MOT's!

I think the only reason they would and could start the bike would be to check the noise level. Even then it would only be fair to let the bike warm up properly.

I'm not even sure the throttle cables are part of the MOT, actually...

Post by **Northern ANdy** » Tue Jun 05, 2007 11:35 am

On mine they just check that on full lock the cable isn't opening the throte valve.

are you sure they dont test emissions? then again maybe they dont. i think iv been on a web site that tells you what they test somewhere im no expert, but i think failing the bike cos it ticks to high is a con why not just turn down the revs.
If i was you i would take advantage of the free re-test then never use the cowboy again plus spread the word about how poor he is.

I've put bikes through MOT that wouldn't idle at all, and some that were round right up to ensure they would.
