fantic 300 pro

Larry, I appreciate your help and interest. Thanks, Paul

I have 240 and 300 Fantics. Both have OKO carbs on them and they run great. They run even better when I use straight race gas or a 50/50 mix. I may pull one of the OKO carbs and try it on my Italjet.

Yes my bike is running. It has a distinct lack of power compared to my Bul 199a and others... It looks like it has a miss match of components in the carb. This is hard to tell as a lot of the jet markings are impossible to determine due to wear. I need to order a whole new set of carb internals from Steve Goode.

My bike has a Dellorto PHBH 28 BS mounted to it. It is in very good/clean condition. I have stripped and cleaned it on three separate occasions. - main: 110 (I think my main is a 115 though this is hard to tell as the marking is worn) - needle: X2, second notch from top (correct needle) - needle jet: AV 264 (needle jet is a AV 264 - I believe the 28MM carb should have a AV 266 needle jet) - idle jet: 55 (I think my idle jet is a 58 but it's hared to be sure as the marking is worn) - idle screw: depending your location around 1,75 turns (correct) Bike has a 60 slide fitted Brand new 200 needle valve and seat fitted as the old seat was badly worn

False alarm on this one.... After spending three prior attempts to get it running I tried again today and it started first kick LOL! Now all I need to do is figure the jetting out as it unresponsive and has very little power. If you fellas have any thoughts/ideas on a fix I would be very greatful. Thanks to all of you for your help and advice.

I have put three new plugs in it and they are all wet after I try starting it. I am thinking the ignition timing needs setting properly.

No I haven't tried pouring a little petrol directly in the cylinder. I have tried squirting a little starting fluid in their. No joy whatsoever. Should I try a petrol/oil mix directly in the cylinder?

My 350T was recently fitted with new points and condenser. After letting it sit for about a month it will no longer start. I have ruled out any issues with the carb. The bike has a big fat blue spark. Could the ignition timing be out?

Can anybody offer any advice on jet size/carbs settings on a 350T? I have an aftermarket Bultaco air filter on my bike (complete with built in rubber boot). New points and condenser just fitted (very nice spark). The needle clip is already on the highest setting. Bike is running very rich. It has a distinct lack of power. It will not rev out cleanly. The needle clip is already on the highest setting. Any advice would sincerely be appreciated. Thanks, Paul

Okay, cheers Glenn.

Will do.

Guys, thanks for taking the time to post your thoughts. I think I will give the springs and caps a shot. Merry Christmas to all!

Glenn, thanks for taking the time to reply and send a pic. Do you have to mod the stock 300 front bracket at all? Thanks again, Paul.

Has anybody tried the adjustable Magicals fork caps and springs on a 240 or 300?

I would like to install a 300 seat onto my 240. Can anybody please advise me on what mods need to be made. Picture(s) would be appreciated. Many thanks, Paul.

Tony, thanks again for help and advice. Cheers Paul

Can anybody please tell me what weight oil I should use for my 1977 TY250 forks? I weigh about 170 pounds. I also wondered how much oil needs to go in each fork leg? Thank for any help offered. Paul

Thanks again guys for your help. I will definately go down the B&J route. All the best, Paul

Thanks to Rich, Dave and Tony for all your advice and help. The reason I want to swap my carb is my original unit is a little corroded around the float area. I suppose I could get away with it?? I was thinking about buying the VM26 then buying all new jets, needle and slide etc (same specs as provided by you guys). Will she run okay? Anyone ever tried a VM28. After much messing my 1980 350 Sherpa T runs great with one installed. Thanks again to all you fellas for your time. Paul

Hi there, Will a Mikuni VM26 mm carb fit my 1977 TY250? Just picked up a very nice low hour bike (318 miles on working speedo). The original Yamaha carb has some wear around the float area. If the Mikuni fits can anybody please give me an idea of correct jetting specs? Thank you for your help Paul

I would like to fit a pair of wider aftermarket foot pegs to my Fantic 300. What are the best available pegs that bolt on without the need to do any major mount modifcations? Thanks, Paul.

Many thanks to everyone for all your help and advice. I ended up buying a pair of 'Gaerne Balance Oiled' boots. Can't wait to get em! Cheers again Paul

I am thinking about buying a pair of Gaerne Balance oiled boots as they have the old vintage look about them. Does anybody know if they are any good? I am going to buy them online and want to make sure I get the correct size. My Alpinestar No-stop boots are a size 10. I have heard that the Gaerne boots are a big fit, does anybody know for sure how they fit compared to the Alpinstar boot? Thanks for the help. Paul

Gentlemen, thanks for taking the time and trouble to help me out. My bike deffo is the model that had the bracket attached to the back of the engine as I have no hole in the swingarm. Unfortunately I do not have the bracket to attach a tensioner! therefore all my bits were a waste of money including the 301 tensioner (see pic) on its way from back home in the UK. http://www.flickr.com/photos/elsinore250/2841469812/

A few more pics of bike and another new chain tensioner I have. http://www.flickr.com/photos/elsinore250/2835731535/ http://www.flickr.com/photos/elsinore250/2835735617/ http://www.flickr.com/photos/elsinore250/2836570848/ Thanks for any help and advice offered! Paul
