Mk R1 Clunky Gears Help?
Just arrived home in my first Kit car ,, Orange MK R1 Advertised on here.
Problem is the gear change is too clunky, not just into first but all the gears up and down again. Aslo i have noticed it wont always move up the
gears with out pressing the clutch.
It realy is a horrible heavey clunk, i called MK who said it sounds like the diff needs fettling, they can do it for a couple hundred quid. Also
called AB motorsport who said i needed one of his fancy rubberiesd propshafts.
It does sound like its comming from the Diff, not sure what to do first, maybe take of the diff myself and get it checked localy as i dont fancy i
ride to MK in the state its in,,
Any ideas whould be appreciated

No offence but if you're new to driving BECs, they can be a bit clunky through the gears if not driven correctly. It could also be a fault with
some part of the drivetrain but it's difficult to know without listening to it or driving it. Why not try and find someone local to you who also
has a BEC and take a passenger ride in each others cars to compare the experience.

its hard to diagnose without seeing the car and experiencing, in my experience of r1s they take a few revs and a wee blip for the first three gears
going up... its hard to do clutchless ups smoothly when youre not gunning it, if i were you id use the clutch for all changes till you get to know the
engine.
try using about 7k revs, clutch and just a quick blip and you should find it much smoother.
where are you based?

Perhaps somebody near you with a bec can have a sit in it and have a listen ?
*Might* just be that your not used to it and comparing it to a normal road car
gear selection ?

As it's your first kit, I assume it's the first time you've driven a BEC. It'll take a while untill you get the timing right,
with the speed of the shift and unloading the transmission, on the changes and untill then it'll feel clunky. Clutchless up-shifts are easier
when driving hard: Getting them right on light load can be tricky and often people don't try. Give it a chance and you'll soon get it.
If you add your rough location to your profile it'll help find local advice.

If there's no TRT or cush in the propshaft line, then it'll 'clunk' a tad. If there's a reverse geabox in the driveline
(i.e Westfield Tunnel Lubricator), then it'll clunk even more. Add all this together with a worn diff and some backlash, and you're in a
whole world of clunk.
If that's not enough, when the various flanges work loose, you'll get a nice rattle and grate to go with it. If you've got a centre
bearing that's not happy, then it'll vibrate nicely too.
Whines (apart from those eminating from the wife), will be hard to locate. A diff. while will resonate nicely up the propshaft, it's like a
wheelbearing, hard to find the source of the noise.
Most noises can be eliminated simply by using the engine like you would on a bike. R1's don't have much torque, so just keep it all above
10K and all will be well. Rattles and whines will simply disappear.
I *have* a wrecked R1 gearbox, sitting here next to me. I can assure you that any fault with the gearbox/engine won't linger, it normally
destroys the engine fairly quickly. I've just bought the two layshafts/gears/drum that were on Ebay until about an hour ago, hoping
they're OK....
If you're around Link Onshire then I'm happy to check your car out in the sunshine, all for a beer.

Funny I've just registered to see what advice there was on clunky Megablade boxes! Mine clunks 1st and 2nd mostly, I have Westy reverse too
which whines and grumbles, the clunks do my head in, but as an ex biker I knew about them, if someone said give us ex-amount and it'll be silky
smooth, I'd pay it, but no-one seems to offer one solution as has been explained already. Ask any biker especially a Honda enthusiast and they
will tell you to accept and get on with it.
Mines done 13k in the car so maybe 20k of hard miles, I'd imagine wear and tear to happen.
I'm getting a lot better with my changes and sometimes they're seamless, but 1st pull away is always a bit shakey, I'm thinking do I
just enjoy it till it blows up? Try a new clutch, look for a younger lump? None of these may get things silky anyway? It just annoys when you have a
few slick changes and then CLUNK again....
I would stick with for a while though Bud before you let it annoy you too much, once mines singing you just hold on tight and grin!

Btw if your near the NW I'm happy to meet up and compare....

Thanks for all the speedy replies
I am based in Warrington nr liverpool. I understand its a Bec and there a bit raw, but the clunking was the same when the Seller was driving, i was
expecting it to clunk in to 1st but was surprised at how heavey it was,, then it did it in all the gears up and down.
Thers no reverse on this one

Its an easy fix.......
ear plugs and a helmet mines got the right backlash in the diff a good gearbox a trt propshaft from bailey morris and it still does it. i think
on a bike the sound is the same but is absorbed thru the chain and much softer cush drive and is not amplified thru the transmission tunnel which is 2
inches from your butt
eerrrrrrrrrrrrrrrr

I'm sure your right! Not the same through a biker boot and your 5 ft away with a lid on, try riding a bike in soft trainers and the box gets a
bit clunkier!
Would love to smooth mine out but it is what it is, and it goes better than most £70k tintops upto a ton and all for the price of second hand
fiesta!

Errrr.... no, having a chain isn't any 'better' as regards the noise. The chains flap around, there is no cush in the drive, again
it's a whole world of mechanical noise.
Difference with a Westerlomkcaterfield is that noise is distributed over the whole car, the only time my front engined bricks were unacceptably rowdy
was with the bonnet off.
My current Midi is in a different league, the induction is only inches away from my bleeding ears. Ouuuchh...
Anyway, if all the BEC thing gets too much, there's probably a nice Megane down the dealers for a PX.

Nah the wife's had 2, I'll cope with my noises, at least you know why your fuel keeps disappearing fast!

Errrr.... yes there is a cush drive on nearly every bike I've ever seen, it's between the rear sprocket and the rear wheel.

Well before i spend any money on it , i am going to drive it up to MK tomorrow morning and get them to have a look,
If it turns out that that its down to earplugs and helemt, it will be up for sale again.. Although i would be totally amazed this is how it should be

If it really is an issue and that bad, a TRT (Torque Resilient Tube) propshaft will reduce the clunking massively and the more you drive it, the
better you'll understand it and be able to prevent it. Unfortunately, it will never disappear totally due to the nature of straight cut
gearboxes.
Give it time and you will be able to live with it..........
