Final Prep

Start Up with Gut Check

Brad was bleeding the brakes and clutch. The old fluid after 4 years was pretty groady. Note: change brake fluid once a year. Everytime you put a new set of tires on. Stopping is important. The rear and front sprockets replaced and a new chain on. All the fairing plastic bits took a most of the evening. All the fasteners and plastic clips. Looks like new. Did not replace the right side fairing. small minor scratches. front fender scratch - but ok. Gas tank ding left side but paint ok. Might change it later. 

The Gut Job

Best part of this whole project. Sure it was overdue for the major tune and valve adjustment. Repairs to all plastic and damage control. But even after 4 years of covering and keeping the bike garaged and mostly out of the rain and washing it - Brad showed me that a deep thorough clean has to be done to really check the condition of every part. 

Back to the muffler gut. The stock sound is so quiet it is as if the engine generated more sound than the exhaust. The V 4 has a low growl now. Not so loud that it would bother my neighbors. Listen to the video at the bottom. At idle it sounds perfect to me. There is that distinct pattern of a growl. The best part is the sound but, also at a quick glance the stock design is kept. There are different ways to gut the cans. The ends of the last exit baffle pipes were cut. The outer tail pipes had to be removed to access those inner pipes and cut. Then we had the tail pipes welded back on. The other guys on the discussion boards used hole saws to remove the tail pipes and did not weld them back in place. I think this extra step is a cleaner solution. It helps carry the exhaust out past the polished end caps. The sound is exactly what i wanted. 

Crank up the volume Bob Varsha.

6-17-12 First Start Up

Valves Tuned, coolant in, tank on

VFR  has the valves tuned and the top bits re-attached. Brad is detailed in cleaning and preparing all electrical connectors and coating tubes and covers with silicone. Looks showroom brand new and happy shiny all over. June 17 - Radiators and fresh coolant. Previously on L.A. Law the brakes and hydraulics were refreshed and bled. Front-end tuned up, all checked to spec and new fork oil. Bearings lubed. 

OEM Honda Coolant

Video of First Start-Up Since the Tune-Up Began

Stock muffler sound prior to the project gut. After the mufflers are removed - we start it up to hear just the headers feeding thru the cat converter. Nice! But, too loud for street use. It does sound like 2011 MotoGP - 800cc V4 Honda power.

Tail Section Fairing, Lights, Saddlebag Frames Removed

Note stainless heat shields and and polished end caps that give the distinctive VFR tail design. I think it looks good and is well designed but is a lot of weight to hang off the back end. The sound is pleasant enough - but the V4 engine has a distinct growl when the exhaust is altered slightly or when you buy an expensive set of mufflers. The problem with a nice sounding aftermarket muffler they do not fill the space the way the stock cans do. I want the bike to breathe easier and tune the sound up a bit - - but not be annoying.

Not a full gut as some would do. I don't want something that harsh. Found details on a discussion board of how this one guy tried just cutting the exit pipes to access the final baffle pipes that can be seen inside the outer exit pipes. Then use a dremel cutting wheel to lop off the final baffle pipes. The exhaust takes a couple of 180 degree turns thru the muffler and removing these final baffle pipes short cuts a turn back into the main chamber.

 Next post should have the gutted sound we are looking for. The exit pipe sections will be welded back on to complete the stock look. Then the plastic bits will be bolted back on - after the sprockets and new chain are hung in place. June 18 is ride to work day. Sorry i missed it but, i will be riding most of the days left in this summer and fall. No long trips planned. But, finally will be back on the road after parking these two wheels for over 6 months. There was a spider living between the mufflers. Evicted.

VTEC Valves Adjusted

VFR VTEC adjustments back to spec

The Service Manual arrived earlier in the week and so the precise adjustments can be done. 

Look at the size of the cam gears and that little chain. Engineered like watch parts. 
Could be assembled this week and riding.

Forgot to add these shots below from the phone.

 Without the skin, tank and seat the VFR looks like a wet dog.
 The engineering and careful design put into every part by Honda is more evident the deeper you dig. Things exist in a precise position and is protected from the elements.
