The v-boost from Gutsibits for Elaine’s bike arrived yesterday and having already fitted one to mine the installation took literally 10 minutes. On firing the bike up cold there was the usual minute or two of fluctuating revs before the engine settled at a nice steady tick over of about 1100 rpm. Pick up was again noticeably smoother once the v-boost was fitted. One interesting thing was that when running side by side (both bikes running de-catted), was that Elaine’s bike without the v-boost had what I can best describe as a slightly ‘tinny’ note to the exhaust compared to mine which I put down to the Chinese, £250 de-cat crossover pipe on hers as opposed to the £700 Mistral version on mine. With the v-boost fitted to Elaine’s bike, the tinny sound has gone and to my ears they sound identical now. Not over loud with a nice little crackle on the overrun. The only other mod’ I am considering is a high flow DNA air filter. The bike in all honesty doesn’t need any more power and runs beautifully now. But it’s about the only thing I haven’t compared next to the standard one. And with the richer fuel mix and de-cat causing the bike to run so much better and more importantly, much, much cooler, I figure letting the Goose breath a little better won’t hurt. Cosmetic changes are minimal, a pair of cheap rubber knee grips from AliExpress to protect the fuel tank and a set of soft panniers for when we go touring next year have pretty much got her how I want her. This bike is definitely a keeper!
Sounds great. Wish you could put videos on so we could have a listen 
. I love a v twin when it burbles as you knock the throttle off. I did similar to a Harley Iron I had about 12 years ago. Proper soundtrack.
Will try and get some footage this weekend.
That’d be great thank you. I wasn’t sure if we could upload video. 
Nice to see one of Prince Philips little cars in the background
Fitted the v boost last week and had a run around Derbyshire last weekend it seemed to make an improvement. I also have a Storm end can fitted. This morning i fitted a performance velocity stack and k and n performance filter. Great service from Gutsibits as usual. Then went to fit the cat delete seems well made and quick delivery from China. After moving the reg rec i can not for the life of me workout how to unclip the exhaust sensor leads. 1 hour later and a cup of tea to think i gave up. Can anybody help me out.
Apparently the connections are beneath the two triangular plastic covers on the frame to the front of the fuel tank. I started taking bits off and said bugger it. I found that as I unscrewed the sensors half a turn at a time I was able to spin the wire where it went up into the frame. (So I didn’t concentrate all the twist in one short area. It worked fine on both our bikes. Screwing them back in was easy as I simply spun the short section of down pipe around the sensor. So no twist involved.
Ah, good idea. It was the first time a Yorkshire tea break has let me down for inspiration. Maybe lack of biscuits.
Thanks for the swift reply.
Don’t forget that “high flow” = less efficient filtration.
Do you really need your thottle bodies coated with grinding paste?
Hi Speedy, As I understand it, the DNA achieves a higher flow rate due to an increased surface area rather than just sticking bigger holes in the fabric of the standard filter. The actual filtration is more effective than standard as it filters down to 5 microns as opposed to the between 5 and 10 microns of the standard filter.
I still have not fitted the cat delete but after having a few days with a cold I decided to take it for a quick run. Wow i can not believe the difference. I seriously think I do not need to fit the exhaust delete. It is absolutely smooth as silk on the throttle, pulls cleanly from 1500 rpm all the way to the red line. I did my test route some fast A road and stop start town roads. Massive improvement all round.
Sounds good, although I noticed a massive difference in the engine temperature after fitting the de-cat. Maybe get an infrared thermometer and compare temperature of engine with cat, then without?
I think that is a good idea i will fit it over winter.
