I believe in a past post beta was mentioned as the swingarm donor.

Excellent, very entertaining

Scorpa 145 piston bores into stock cylinder. Scorpa 163 uses a oversize sleeve, case boring required. 190 cc piston kit available from small Yorkshire engineer, lots more bottom end torque but wont rev up like 125,145,163. Nigel Birkett Scorpa importer, scorpa 125 guru, finished several Scottish 6 days on the wee scorpa says the 163 cc version works best overall, he doesn't like the hugely oversquare 190 kit because it wont rev up properly. Lovely bikes.

As jer says, my 315 had two pilot jets. One was well hidden if I recall, been a while since I owned it.

They use 35 x 47 x 10, very common. The width is not important, ie 9, 10 11 mm all work.

Congratulations, they are a great bike. Im sure you will enjoy it. Probably a good idea to check the waterpump impeller.

Honda reflex are 33 mm, TLR 200 competition are 35 mm

Completely normal on the monty, designed that way. Don't mess with it.

Hi, I have a set of 305 Fantic forks on a twinshock Honda and a set of 303 Fantic forks on another twinshock Honda. The 303 forks have identical parts in each side or said another way, both sides have compression damping and rebound damping. The 305 forks have rebound damping on one side and compression damping on the other. When the 305 forks are disassembled they look very different inside, right side to left. The left side uses a 1/2 length spring (rebound side if my memory is correct), compared to the full length spring on the right side (compression side if my memory is right).

Yes sounds like a xl185 engine (180cc) in a TL125 frame. Honda never sold anything like a TL180. I have done 3 of these engine swaps myself over the years. Although I always used the xr200 engine into the TL125 frame.

Not sure of the rider, but that's another Bultaco Sherpa T, Derek. Theyre everywhere.

The starwheel on the end of the shift drum can wear (not visible to the eye) and cause less precise shifting as time goes by. Part # 24411-446-650 called gearshift cam by Honda, also the gearshift plate 24621-446-650 which fits over and contacts with the starwheel is commonly replaced at the same time. These parts are under the clutch and not hard to replace (no splitting cases). There will be no discernible wear on the old parts but often replacement can make a huge difference. A lot of information on this on some enduro sites, same parts on XR200R.

What model fantic, older twinshock, air cooled mono or modernish section?

You have a plugged pilot jet. These bikes are famous for carb set up issues. Comes from having such a large carb on small displacement engine (32mm Kehien FCR )

Post 36 is a Bultaco Sherpa T

I think you have to pay up nigel. An fellow club member here bought a 2014 scorpa two months ago.

Glad you found the problem, had the same result as you with my montesa 315 10 years ago when I submerged it.

You haven't said what you found when or if you checked the reed valve petals .

The brake discs on your fantic came that way from the factory glen. Changing the bushings will make no difference. The 38mm Paioli fork, ajp wheel hubs and brake discs on your 90's era fantic are exactly the same parts on the 97-99 montesa 315 incidently.

I thought the same, before pub. Great project though.

If it was running when it went under water, it could be damaged reed valve.

Sorry to see your new to you beta came in such a state. Good to hear the selling dealer and previous owner are paying for the repair parts. Thanks for posting about this racing clutch so people are aware.

The 311 cota was made in 1992-1993 and was known as the last of the REAL montesas. It was called that because it was the last montesa with a Spanish engine. 1994-1996 was the 314 with the first Japanese engine in a monty. 1997-2004 was the 315. A friend has a 311 and likes it, gets parts from suppliers in England no problem.

They have 8 horsepower. I have competed on one for over 20 years, first with stock engine, then bored and stroked engine (175cc) and now XR200 engine. If you are not too big and heavy it will be fine to start on. Ultra reliable, low maintenance.

bought many parts from them over the years from overseas, always very happy with service, prices, shipping etc. If they cant make a go of it with their experience and size, its very sobering.
