Markz9

He has a wooden former he uses for the sections of the tank i have seen something posted on faceache or youtube of him (ETTO) making a gs1000 tank

any more update on this, i have my srad 750 and slabby 7/1216 race bikes to stretch their legs at cadwell

The later cr had that setup the tank is just a cover over a steel tank

Hi yes it’s an original fibreglass tank it is possible to get it lined I’ve found a chap in reading who does it and pressure test after

The down side of several projects on the go at once means I have long gaps between updates so to make sure I got the back wheel in alignment I dropped the bike over to Debben performance as they have a lazer alignment I had already sorted the front end with a new spindle Sam made for me at this point it looked the frame was bent as the rear wheel would not align then we discovered the disc used on the swing arm pivot was a 6 and a 9 which meant the swingarm spindle was skewed pushing the arm out

For the Harris and rickman I’ve had a few parts I could start getting made up so I cornered rsvfletch at the Suzuki Cadwell meeting and persuaded him to alloy weld the difficult parts as usual he has done a great job and are ready to collect at Stafford show the oil catch tank will fit inside the rear of the Harris seat sub frame, so I sent a bag of bits and Steve made something useful out of them the sheet is 1.2 mm so nice and light not so easy to weld couple of clutch covers fitted with secondary breather outlets and the bandit 12 arm is an alternative for the rickman but need shock mounts fitted

Little bit of an update the rickman has had its full fat engine put in, a few issues with lining up the rear upper engine mount and the swingarm pivot currently lining up front and rear wheels with the associated sprocket and chain alignment Ray Debben performance is helping with this as he has a lazer alignment tool over the years I’ve some horror stories there where owners have come in and asked why the tyres are wearing a bit funny or it doesn’t like left hand corners, bike fitted with a 6 inch rear wheel which shouldn’t be possible and isn’t as, wheels out of true by a 100mm and they rode the bike there!

Had the additional bracing added to the headstock of the rickman plus some repairs etc although I have since found out that part of the problem is the different materials used between the frame tube the headstock ie it’s not all chrome moly john is very good one of the best I’ve seen

Hi no it’s def brazed the def of welding is ‘join together metal parts by heating the surface to the point of melting’ since the tube in Harris and rickmans is chrome moly with a melting point of 1429 deg c and bronze filler rod is 890 deg c it’s not welded but joined by filler braze obviously you only heat up the filler rod till it melts another reason is at the point of melting chrome moly tube (for building bike frames) you actually turns it back to mild steel for approx a 3rd of the length so a very triangulated frame such as a Krauser bmw might as well be made of mild steel tube I did chat to john on Saturday in fact he does use an inline flux pot, I will get some better pictures when collecting my rickman frame and I will try and find the article you have mentioned.

Hi all the rickman and Harris frames are brazed as they aren’t melting the tube and use a bronze type filler rod apparently it’s the type of flux that makes a big difference and the manufacturers keep changing the chemicals as elements get banned by the eu etc both John and wasp dip the rod rather than flow the flux in the acetylene gas which I am pretty sure Harris do i can do it my self but not neat enough to be in show !

This is the rickman as it currently is and these are the additional curved braces that were added on the very last production cr and also retro fitted although I am getting these brazed rather than welded

So I decided nipped over to Sturminster Newton and jhr to collect my Harris f1 frame John builds a lot of motorcross frames for competition bikes and originally worked at wasp and his sif brazing is excellent plan now is to trial build the whole bike I ve hopefully added all the additional mounts for oil catch tanks etc next job is make sure the front and back wheels are in line and a chain will align with the engine I am also dropping off my rickman to have the extra stiffning head stock tubes added the original rickman cr fram s started to suffer with cracking as the engines started to getting more powerful and I intended racing this as well so might as well get it done at the same time and then nickel plate the whole frame again

The forks are new and 35mm longer longer than standard so should help with me decking out the engine cases and the super slippery ti finish didnt add too much to the bill i am robbing the dymags from the slabby race bike and i have some p4 brembo's with sams adapters, so could get the Harris on its wheels fairly quickly

Forks are back from Maxton I have gone for the compression and separate rebound damping and my frame mods are done

Had a quick look through the weblike web site and found the Yoshi cover are still listed you can never have enough bling although the points cover is still not available so I am going to have to keep looking
