    Fuel pump

    This is it. Electrical connector is correct fit. https://www.ebay.co.uk/itm/255523655934 I also bought an inline one as a back up but didn't use it. This doesn't seem to be available anymore for that seller. Looks identical to this one similar price. https://www.ebay.co.uk/itm/364105127098

    Fuel pump

    I don't know if older V-maxes use the same as my '98 but here's a link to pt1 on how to get the cheaper fleabay ones to fit perfectly. I haven't run mine much but haven't had any issues with it so far. if you have no luck finding one I'll see if I can find the listing for what I bought but is...

    engine not revving and sputtering at 6000rpm and above

    Aside from the previous comments I'm wondering if the mods have just altered the scavenging phase to the lower rev bands at the serious expense of the higher ones. In that case there would be no mitigating mechanisms built into the exhaust/intake systems available to the higher rev band. Going...

    Water in the engine oil ? (Gen 1)

    Pretty much all the short run time has been to check everything is back in place properly, not leaking and actually works. Advice noted. Thanks. Thanks everyone helping put my mind at rest that this likely nothing serious. I'm looking forward to being able to be actually going for proper rides...

    Water in the engine oil ? (Gen 1)

    Yeah short run time has been very much the norm, there's been so many things needing attention, most recently carb's (again) & rr brakes. Stored in unheated garage. There has been some very slight coolant leaks from the rad drain cock valve & an associated pipe, which are next on the list to...

    Water in the engine oil ? (Gen 1)

    Changing out the clutch cover today (orig was cracked & leaking) & noticed what looks like some drops of water in the oil drippage. There was also some white stuff (water/oil emulsion?) on the inside of the old c/cover. Didn't see anything like this when I changed the oil mid 2022. Hasn't been...

    Rear master cylinder recomendations

    Update for anyone following: Well it looks like the trike guys win. I bought a s/h oem m/c & it did absolutely diddly squat. On full stroke wouldn't even start to operate the rr brakes. So I've made up some new bracketry for the 3/4" / 19mm clutch m/c (which I now believe is from a Fiat Uno)...

    engine not revving and sputtering at 6000rpm and above

    I managed to pick up this Marving unit quite cheaply on fleabay for my Vmax. It is European approval E3 Cap. 9. & requires no mods to anything else. It's Italian made so I'm presuming it's homologated (I've learned a new word). Not cheap new but maybe worth keeping your eyes open for secondhand...

    engine not revving and sputtering at 6000rpm and above

    Watch this on exhausts (from 4:00 min). Exhaust are tuned to give the negative pressure (part vacuum) at certain rpm (usually high) to draw out exhaust at overlap (this known as scavaging). As explained in the vid this means it can be out of phase at lower rpm (usually mid range). In V-max case...

    2004 fuel leak

    Joseph Whitworth was the 1st to have a standardized screw thread adopted as a national standard 1841. He was born in Stockport (Manchester) England. Mass production of identical parts was 1st achieved in the manufacture of ships blocks (block & tackle) in England in the late 18th cent & into the...

    What did you do to your Vmax today? Part 2

    Made a bracket for the rr brake fluid reservoir.

    Carbs and exhaust

    This is just what I've learned from youtube while doing my own carbs, airbox & exhaust: Airbox is designed as a resonant chamber. It means it's set up to provide positive (increased) air pressure to the velocity stacks (the long rubber things) at certain rpm (usually low/mid range). The...

    vmax rattle noise

    Does it go away when you pull the clutch in?

    What year is my engine?

    My frame & engine numbers do not match either. It's 1998 & both have the Canadian 2LT (N) as part of their numbers. Date of 1st registration is 1998 & date of 1st reg'n in UK is the same, declared new by the independent importer so unless it came to the UK from Canada (or ?) with a spare engine...

    Show me your scoops.

    Yeah that's them, injection molded plastic. Luckily I quite like 'em. Quite liking those front fairings too.
  16. 3-Max

    Show me your scoops.

    I've seen lots of pictures of Vmaxes over the last 6 months (+ a couple in the flesh) & noticed several variations of scoop but none like those on mine. I've an alleged Canadian import ('98) with plastic scoops. I'm sure there are others with these but are they specific to Canadian models...

    What year is my engine?

    Interesting thread guys. I'll be looking at mine as it's allegedly a Canadian import.

    Rear master cylinder recomendations

    Yeah I am suspicious. The chart & every calc I've come across (2 of) are indicating 12mm or lower. Given the front end has 14mm M/C working 4 pots with an ave size of 32mm, a 19mm M/C for 2 pots at the back seems excessive. 19mm maybe good for a car but there are lot's of other things to...

    Rear master cylinder recomendations

    Well checking with trikers has just confused me. Over there they're talking about 3/4" (19mm) or 7/8" (20.5mm) as what should be used with this set up but I've only a couple of replies so far. I think I'll get the exhaut & carbs fixed 1st then investigate what it is that's I've actually got...
