Roo's Viffer

[Laverdaroo]

Well I hoped to be posting a few shots of a sea of bikes at Squires Milk Bar at Sherburn in Elmet, last night but sadly, Houston, we have a problem!

The first time in 21 years Rosey has stopped a journey through failure!

Just got through Boston Spa, opened her up on the nice fat A road and a plug gave up and she started to pop on 3!!! Bugger.

Limped 22miles home on three pots and currently trying to find 4 plugs to get her fettled for the long ride home. Naturally these are the hardest plugs in the world to find unless you want to spend £29.40 each on them………..nope not I!

Found three, just need one more!

Bit of a worry as it’s either a plug or a coil……. Hoping on the former rather than the latter but a poke about will no doubt identify the issue……..fingers crossed!

Cheers but Boston Spa, North Yorkshire, near Wetherby. Managed to get some plugs at great expense so starting there. I’ll swap the coils round and see if it’s one of them if not plugs but might be as have one cold pipe  on number 3 at the back.

Open the carb drain screws and see if it's not petrol related first. Presuming it's one of the carb versions of course.

Speedo would have been an optional extra on the Sunbeam

It had been fitted Bryan, first thing I spotted was the drive gear inside the front hub, the cover is missing as you can see and it showed signs of being fitted but then removed. Same for where the speedo used to sit, signs of it being there. I concluded it was away being refurbished but he still wanted to ride the bike.

FI bud, I’ve part numbered it about and it appears from Honda, £176.87 but as the Honda cuvic shares the same pack, £48 from euro, delivered if required.

Just getting into it now. But running on three, soon as you open it slightly, it bangs like crazy from the pot suspected. I reckon either no spark and the unused fuel’s hitting the pipe when hot and popping. That’s coil or plug to start on…….
We’ll see shortly

Very rare for a Viffer to break down Roo although yours does have some miles on it so maybe some components are just getting to that age to call it a day. That's a useful but of info about the FI, do you know if the same part fits the Fix models?
Cracking bikes there Ken, the Morini is very sweet, they were always great looking bikes and especially the 350 Sports although twice the price of a Norton Commando when new!

I too wondered exactly where he was Julie, would have been nice if he had been close to you

[Sesman]

Yes, that would have been handy Bryan.

[Laverdaroo]

Nooo, that would be far too easy

Took the coil pack out and the plug came out with it. It appears. The only time it’s had its plugs changed at a shop was while I was in hospital a couple of years ago, the gorilla tech had caught the thread and slammed the crooked plug into the thread and tightened the coil down onto it. The electrode has arc’d so much it’s melted and sent all the molten shit into the thread. I now have to find a spot where I can pick up an M10 x 1.0 metric fine tap tmrw to try to get a plug down far enough into decent thread to catch and seat properly. The heads got to come off anyway so I’ll get it sorted but just need to lump it home for Sunday mornin. My pal here has donated his MT09 for parts chasing bless him


Check that out for a hammered plug!

It’s some 750’s Dave but all the Fi and VTEC up to 09
