- I've been looking to have a go at building an exhaust for a while now so this seemed like a perfect opportunity.
This is most definitely not a how-to! I'm simply having a bit of fun in the workshop, learning some new techniques and brushing up on my Tig welding skills which as you will see is desperately needed!
The simplest way to do this job would be to buy pre-formed bends and join them together. This would probably be better for airflow also.
Nice work mate!:)
Thank you!
Try for 3 litre capacity airbox, and use a Sherco element
Thanks for the comment! Currently running a 3d printed Airbox that's 1.7 litres with a techno 250 filter. Is there a calculation for working out the optimum volume? I've a few tweaks to do but I think il be hard pushed to get 2 litres fitted in there!
@@owensengineering286 To fit a big airbox, you need to cut away the mudguard and oil tank mounting brackets, the back of the airbox forms the lower part of the mudguard. A VForce reed block, reed spacer, and port changes, as well as a big airbox, transforms a 175.
Ah makes sense. Mine is a Godden framed 200 so don't want to be cutting it, I'll fit what I can into the current space. Currently running a RD350 inlet rubber with a 26mm flatslide and boysen reeds. Definitely makes a big difference. Currently looking out for a spare top end to play around with some porting. Reed spacer is interesting, I had planned to make a boost bottle, a few guys I know swear the boost bottle smoothed out the bottom end and removed the little dead spot before the 175 engine picks up. I guess the reed spacer may do the same job!
@@owensengineering286 Do you know much about 2T porting, and have you got the tools needed to do it? The DT100 reed block fitted to TY175 is very restrictive, and if you can open the intake duct, can be replaced with an RD250/350 block. Most TY175 running issues are due to the very restrictive intake systems fitted. With a large volume airbox, and proper porting changes they can be transformed.
@@owensengineering286 Bigger airbox helps to provide a wider power band. Airbox that is around 3 litres, VForce reed block, reed spacer, 26mm carb, and short front pipe, will improve it a great deal.
Nice work! Sounds more like a big bore bike 👍. Time for education- what’s the Majesty? I’ve seen it w/the European TY’s . Thanks
