    There is no silicon based release agent, it's the biggest myth and misconception out there. I think it may have been used a few decades ago?

    Even scrubbing in tyres, people over think it. I can have a brand new set of tyres, ride out to the Twisties (20kms away) and have it knee down, 52/54* lean angles with no dramas.

    Bikes back on deck.

    134hp 120tq.
    The TBR exhaust is hurting the TQ and drops off a bit before the cam rolls on at 3500rpm, so needless to say Ill be selling a 2000km old TBR turnout exhaust once I work out what full length 2:1 system Im going to run.

    Also got another surprise coming in the week or too

    Hey 120tq aint a wimpy effort......most 2-1 have a breath before they start pushing hard

    it pulls and then some. Just easing into throttle response to bike hp through the bends over the next few days.
     I dont exactly want to throw it into the trees

    Nath 103 how many inch's is the motor? I used the S&S 625 cams for a while on a TC95" did not have close to that HP. but I had high comp. I then went back to Andrews 55G & did some tricks to the manifold ( was a carb motor ) I used to drag race this bike as well as ride it. So I got to compare looking at ET & trap speeds 1/4 mile. I was getting higher trap speeds at drags with the S&S 625, than with the Andrews 55G but was getting quicker 60 foot times with the 55G, then did a few tricks I thought up to the intake manifold & changed the jetting in the carb. & got the 95" to do same trap speeds as with the 625's but quicker 60foot & quicker ET with the 55G then same trap speed so 55G worked for me. went good for a 95" 11.2  @ 121MPH was best I could do, but with 121mph could have got high 10's if I was good enough. with the HP & TQ you have could go quicker & faster than I did, but it is not easy.

    Krash the motor is at 117 with a 635 cam instead of the 625, heads, tb, crank, and clutch all done to take the loads
    Was only going 625 path if I was going to build a 110 but for the extra few bob 117 was well worth it. 

    Ive got a few mates with Stage 2 M8's and there at the same TQ but only 105-110hp, which by no means is a slug, but they have room to continue to build.

    The misses complained when I originally got the SG it was a bit poxy as a 103 so I built it for 'her benefit'!!!

    I have plans to take it to run it on the 1/4 mile but as the whole motor is only 1700kms old Im just going to enjoy it on some long twisty day runs before I do that. I do want to do a couple laps around Eastern Creek to fine tune the suspension, and add a GPR steering stabilizer to tighten up the front end at higher speeds of 160kmph+ that are performed on a 'private road' 

    Overall massively happy with the bike and Im still ahead in $$ than buying a stock 114 M8 Streety with the same amount of kms.

    Good stuff! sounds good to me. the drag strip Sydney has a meeting planned December & with the brand new race surface, is the best track in Australia.
    good idea to test it on private road!
    Enjoy it!

    Hi Nath
    I’ve always been really curious about the s&s635 cam which isn’t used much, especially in Australia. Used by a very reputable harley engine shop in the USA, star motors who the owner is closely related to s&s. The cam specs are different from the norm so would like to know more about your build in terms of set compression, head work, what pistons and do you have a dyno chart to have a look at. Also curious if you had any bottom end work done but assume you haven’t. 
    Cheers

    Was sitting in my mates ute in the Kalgoorlie Yamaha dealers car park having a smoke while he was inside arguing about (ironically enough) tyres peeling on his new 420 and the lady dealer and the salesman were delivering an R1 to some cocky prick out front, couldn't really hear all the talk but I did hear her tell him to take it easy on the new tyres more than once, he brushed it off, took off up out of the car park heading west, gassed it, went down, they rushed over and wheeled it back into the shop, amused me no end.

    Bottom end is done as I wanted it built right the first time. 
    Compression ratio I have no idea

    To make it easier for the forum, is it possible for a moderator to delete this thread & I'll make a new build post as this has diverted into talking about the bike and tyre mould release agent

    2 weeks time it’ll be a bad dream and someone will ask “anyone know anything about s&s 625 cams?”
