Laverda 750 SFC 1974 replica

Not a "Knee dragger" (occasional g/box cover though) but got good results with AM22/23 race compound on both twins & triples. - regards - Phil

:D  Yes i found in couple of topics that a lot of racers use am22/23 but out of my budget at this moment am22 costs 230? and i cant get am23 here in Slovenia. 

Phil what width are you using 110 and 140?
 
Hi Luka - 110 & 130 - Classic racing rules in UK limit rear tyre size to 130. I don't think I'd want larger on the 750 anyway - regards - Phil
 
If you can source Bridgestone BT12SS you can experience awesome grip, wet or dry!

As for using all the tread... wasn't even trying!  :D  Don't want to drag my knee either, not too keen on ruining my leathers.

150/80 on 4.00" rim.

Problem is that they don't do it in 140...
 
For my money the tried and proven Avons or the new kid on the block Contis, don?t be put off by the price, they are cheap compared to a crash or frustration, and I am sure you?ll get someone to freight to you. Is there a racing forum in your country?
What size rim are you fitting to? Unless you use a tyre the correct recommended size for your rim, err in the direction of a wider tyre on a thinner rim, it is no good going with too wide a rim for the tyre.
And even with your hot big bore motor, you won?t have the type of power to need or use a big tyre like a 140. Have a look at the pics of the worlds fastest SF racer of SteveB (Breganzane), you can easily see the rear wheel in the pics on his website.
 
gonna try the conti,s meself in a change or 2-avons will be hard to beat i reckon-but i like the look of those conti,s-sizes are right up my alley
 
reckon youll be rite mate-a 150 leaves me 10 mm gap to chain ,but as you know me arms a tad wider than yours
 
I was a Pirelli Radial Phantom fan way back when - But, Oh Hum, they don't make 120 x 80 18" rears any more and neither do Bridgestone make BIOS in that size - SUCK and SUCK.

I now run a 110 and 130 x 80 18" BIOS Bridgestone on front an rear but find it rather cumber son  to roll over in the corners.

I suppose I'm over tired and should have commuted to a 100 Front and a 110 Rear x 80 18" BIOS Bridgestones - But I did love that old Perelli Phantom Radial 120 in the rear of my SF.

Perille did at one time make a nice Radial 110 x 70 18" but it cracks between the pads after a year as our Borrani rims as just too narrow - Don't ask me how I know - LOL.
 
well Ron, youll be happy to know that the new Contis we are talking about are radials, and they have them in the appropriate size that is suitable for your bike
 
Geez! COSI - You want me to spend another $400 on a set of Conti's for next season when I got a brand new set of over sized Bridgestones Bios's on her - Your a Cruel Man but I'm happy to hear Conti has our beloved 100 and 120 x 80 x 18" Radials.

If I recall Contis where great on a 71 750s Beemer.

I could never understand why our Breganzies came with Metizlers that melted before the end of the summer. Gotta say you could show off with them Metzlers and smoke them through 1st and 2nd - LOL

Are these the Cont's you referring to:

100/90R18 M/C 56V TL

110/80ZR18 M/C (58W) TL

120/70ZR18 M/C (59W) TL

130/80R18 M/C 66V TL

Kinda like the looks of that Conti 110/80ZR18 M/C (58W) TL / 120/70ZR18 M/C (59W) TL Combo ;o)
But would suspect the Pads to Crack with at 120 x 70 Profile over our narrow Barroni rims.

Considering Bridgestone don't Mfgr the size of tire I want these Conti's Radials look appetizing.

I don't know what cilinder and from where it is from. i received it with a bunch of spare parts that i bought.

Only thing is that it was made for bike that had brake on right foot not on the left.
 
It's time to start searching for carburetors. I need 36-40mm carbs i was reading some topics and i find out that mikuni carbs are good for preformance. But there is a lot of different mikuni models? So what mikuni model i have to buy?
 
I have Mikuni RS 36 carbs on one of my triples.
I'm sure someone more experienced in carb swaps for the 750 will be along in a moment, but I would think the RS 36 would be a good place to start? Maybe 38s?
They are available cheaply on ebay or brand new from Topham.
