why not then, huh??!!?? [Image: whatcha.gif]<!--QuoteEnd--><!--QuoteEEnd-->
that was kinda my thoughts too [Image: unsure.gif]

is the mk2a fuel pump same as the R6 one?

it could be just because of availability....there are a lot more trashed R1/6s than there are mk2a TDMs [Image: rolleyes.gif]

Hi
My TDM is a MK1 ( P reg ) 1997 with the vaccum pump I'm in the middle of fitting a 1998 R1 electrical pump and so far so good, the wiring and relay wiring instructions on this form have been great, "THE PUMP LIVES" tonight it's just a bit of piping to do I'll let you know how I got on

P reg would be mk2 (or a very late registered mk1)
see if you can pick it from this list?

I'm coming to the conclusion that (in the UK at least) these things moved so slowly out of the showrooms that they were often registered one or even two years after the date of manufacture.

trying to hunt something down nearer shock, batt, fuse box end as thats where I've got loom for fuel pump.
was thinking tee-ing off from R brakelight switch feed...

tho light has stopped play for today<!--QuoteEnd--><!--QuoteEEnd-->


Job done bar road test , took feed from R brakelight after made an extension piece
then corroded brakelight fell apart..... b*llox...another bit to fix

cost of TDM elec fuel pump new would be interesting, found pringle(?) solid state replacement pump for around £42 yesterday, not bad considering ebay R1 prices + it looked smaller (http://www.vehicle-wiring-products.co.uk/VWPweb2000/hoses/hoses.html scroll down to Facet fuel pumps)

Mk1 TDM850 Electric Fuel Pump Install - Beedenb - 20-04-2007

Hi all,
My bike is MK2 sorry for the confusion. 1997

Well I fitted the 1998 R1 pump yesterday , only to find that the bike was getting very hot on the RH cyl and back firing when the rev's dropped off, the top speed I could manage was only 105mph.
I'm not sure what's causing the problem with the R1 pump, anyway I changed the pump back over to the std vaccum type and all well , I gained another 20mph with no back firing.
I'll test the bike out for a couple of weeks before I decide what to do with the R1 pump. You may see it on this forum

Question.
With the R1 pump fitted could the petrol flow be too great for the carb's causing the back firing , but why only the RH cyl ? I do have twin Lazer Proline racing exhusts fitted.

Hi
I fitted the R1 ( 1998 ) pump with in line filter & relay on my 1997 MK2 as decribed above on this forum but found the petrol flow rate was to great for the carb's and the down pipes were getting very hot. ( RH Cly )The exhausts were also back firing when you lowered the rev's. to an extent that it was unrideable - It felt like I was riding on full coke.
Any idea's to rectify this ?
( At present I'm running the bike back on the Std vaccum pump )

Mk1 TDM850 Electric Fuel Pump Install - jht - 02-05-2007

Hmm
I got Laser pipes and had no probs like this! Runs ok except for a vibration that seems to have appeared [Image: ranting.gif]

No backfiring, hot running etc tho' [Image: doubtfull.gif]

Mind you, what else gas been done to yours carbs-wise if you running open Laser pipes????

I've just set the fuel levels, float heights had been around 13mm, had to drop them to +/-9mm to get the right fuel height tho, and just about to go balance carbs. (Roadtest will be tomorrow now, pants as was great day for a spin!)


Oh yeah, priced up brackets, pipes and 'leccy pump from 99-00 TDM.......




Around £200




That puts paid to that one then!!

<!--/colorc--><!--QuoteEnd--><!--QuoteEEnd-->


Ok scrap everything I said re carbs ok

I live & learn....

Set fuel height as per wkshop manual, did it off bike on bench

everything hunky dory

fitted carbs & ran up with remote fuel line NOT via pump

all OK

hooked fuel feed to pump, turned on fuel and igntion


Fuel pissing everywhere

Recheck heights now carbs in situ.. ok

checked them with pump on, and they over by around 5-6mm

Aaaarrrrrrssssseeeeee [Image: ranting.gif] [Image: ranting.gif] [Image: ranting.gif]

so gonna have to drop carbs, rest fuel height around 6-7mm lower than spec and try again

bollox

Spec is aboot 11-13mm? You changed them by 9mm???? [Image: blink.gif]

Mk1 TDM850 Electric Fuel Pump Install - jht - 02-05-2007

Nah, dropped 'em to 9mm, so 2mm under spec, to get correct fuel height

they were at 13mm, fuel height was 10mm below level (spec is 15.8-16.8mm for Mk2)

sure we been thru this before, but where did 11-13mm float height come from, as Yam only list fuel height spec??

anyway carbs off and goin to drop fuel height to 23mm (so gonna go for 11mm flaot height roughly) gives me a 5mm head for pump pressure and that'll hopefully stop leaking











ever wished you'd just left it all alone....... [Image: unsure.gif]

Mk1 TDM850 Electric Fuel Pump Install - dapleb - 02-05-2007

Ahh ok you were talkin fuel height snot float height......spec for float height is about somewhere, think its also on Factory Pro website.

Mk1 TDM850 Electric Fuel Pump Install - jht - 02-05-2007

Right that seems to have done it

Float height set to 11mm on bench

didn't bother checking fuel height on bench (tho had set fuel height guage to 22mm)

chucked carbs back on (without connecting cables etc).....

Hooked up pumped fuel feed, turn on ign, checked fuel height with pump on.....

















fecking spot on 16mm below Mikuni line, no leaks anywhere [Image: yahoo.gif] [Image: banana.gif] [Image: yahoo.gif] [Image: banana.gif]


carbs balanced, bike together, road test will have to be commute in tomorrow...... finger crossed [Image: angel.gif]

Mk1 TDM850 Electric Fuel Pump Install - wicklamulla - 03-05-2007

that'd be new Tony, i may have a guy selling those parts secondhand from a 99 MKIIa, oil contact him and see if he still has em.

cheers mate, think i'd rather go with a mk2a than an R1/6.

Well she got there and back, no fuel leaks, no splutters coughs or farts, noticed a litttle hunting this am on M3, but not this afternoon on way home.

But seat of the pants input is that she revs noticably quicker, seems to pull stronger and cleaner.

She smells a tad rich, so as the jetting for the Laser pipes was guess-timated I'd really like to dyno her now.

(I notice stormy lists his trixie as 94bhp, now that'd be a fun targert for TDM..... And whats this CDI white wire / low gear power restriction thang???)

Mk1 TDM850 Electric Fuel Pump Install - crazymanneil - 05-05-2007

I've just completed install of R1 fuel pump on my mk2 850. Seems to be smoother power delivery with no hesitation on acceleration like before. Not sure if it made a difference in torque down the rev range or speed up top but happy enough. Next step will be a decent exhaust [Image: rolleyes.gif]

I didn't put a relay on and mine seems fine. Started out trying to tie to wires going into the CDI and quickly found out that the current on them seems to pulsate when the engine is running. Might also be the cause of others having backfiring and running on one cylinder. I ended up tracing the loom from the right hand bar controls to the plug under the tank. A few tests with the multimeter and I took earth from the black wire and switched live from the red/white wire (there are 2 of these - i used the one in the middle of the connector). So far so good.
