Prutser's bike stinks....

After talking to Airhead Wrangler about the difference between a reinforced and a non reinforced frame I thought to give it a go and do some welding on the poor old ST.

Because I use the bike pretty often and I don't have time to do a complete rebuild I'm doing the reinforcing bit by bit.

I took off everything around the headstock to start on that part first.
Asked a friend of mine if he could sandblast the front of the frame to get the paint out of all the hard to reach places.

So that's what he did.......



After the frame was sandblasted I could start to make some plates.



If I have to do this again I know for sure that I will take the whole bike apart. It would have been so much easier to put the frame up-side down instead of me being up-side down staring into a black hole where the welding needs to be done



Another good thing about taking the whole bike apart is that you might think about removing your hidden stock of tyraps out of the main frame tube before you start welding. Now I noticed they were still in there because of the odd smell and black smoke that was filling my garage



So far I still have a bike that goes straight forward without making two tracks next to each other

I love projects that take twice as much effort as should be needed. Should be an Airhead motto.

Prutser-having looked at your various threads, and particularly the Sibirsky Extreme thread; you do some awesome work!

WOW! You'll be finding sand all over that bike for decades. Every bit of exposed, and then some, grease and oil must be packed with sand.

My thoughts exactly. I turned down a R90S project recently because the PO has done some cosmetic bead blasting to the engine. Well maybe that black covering over the engine will help a little bit.

Looks good! I wouldn't think there will be more sand than he had on the bike after the latest big trip and that seemed to turn out okay after a wash. Looking forward to hearing about it all works out...and seeing if you make any design changes to the plates and locations when compared to the the standard placments.

If you've blasted in a booth before then you'll be familiar with a man-made sandstorm. Notice that the operator has on PPE. There is a reason for that. Sand (or whatever media is being used) will find every nook/crevice and fill it. Grease and oil is the ultimate sand magnet.

I had a '72 Bonnie oil-in-the frame have its frame blasted. The blast operator blew off the fill plug and strainer seal while still blasting. He didn't think it would be a problem to keep blasting away. The oil tank was rinsed and purged numerous times. The oil pump died real quick after the rebuild. The oil filter/strainer was pushed to its limit.

Maybe Prutser is going for the stinky and 'gritty' combined effect.

I know its stupid to have the bike sand blasted like that.
Over the years I have done a lot of airhead re-builds and restorations that included glass blasting all the engine parts. So I know where you can expect to find sand or glass.( everywhere that is) Whats even more surprising is that it can still be there after you have washed the blasted parts 10 times or more.

One time a guy asked me if I wanted to put his K75 back together after he had everything sand blasted. But when he showed me the whole drive line still in one peace with all the bolts, seals, injectors and some cables still atatched
I asked him if he needed help bringing it to a junkyard. some guys told him it would be fine

With my bike I took the risk of blasting it like this. Most parts were taped or sealed and for the other parts of the bike it was a good way to get used to sandstorms that is will endure on one of my next trips.

So far I didn't have the time to test ride the bike yet and I still need to do the parts around the swingarm pivot points.
I'm trying to make plates just like HPN does them. On a few bikes done by some boxer specialists I have seen broken reinforcements or broken welds. So for now the HPN style is the safest way to go imo.

New luggage racks

So far I haven't had the time to finish the rest of the frame reinforcements because I needed to make some new luggage racks first.
The ones I made before were ok but I wanted to have the weight of my luggage a bit more forwards and a little bit lower. So I made some new ones.

The old ones looked like this:



The new ones are much bigger for better support of the soft bags. And that makes them heavier



I'm happy they don't make the bikes ass look too fat



Now I have to wait for them to get back from the powder coater.

Hi Pruster, Is that a carbon fibre tank. ?
